How do you know if a graph is linear?

It's curved. Take Newton's second law F=ma, therefore m is proportional to 1/a and therefore the graph will be similar to a y=1/x graph and will be curved.\n\nTake F=ma, so m=F/a, proportionality is about if you double one thing the over doubles, however this is inversely proportional so if you double m you get a half of a, this is assuming that F is a constant.

you mean f(x)=3x+2, for example?\n\nreplace f(x) with Y, graph and solve as a normal equation. Linear functions have infinite whole solutions, depending on what you want Y to be.\n\nOf course, I could be minunderstanding you completely. If so, sorry.

Plot and analyze different types of graphs. Graph Plotter can also find asymptotes of function, break points, extremums and calculate limit, define integral and derivative of function.

The slope of a line can tell you how to get from one point on the line to another. If the equation is a linear equation, a straight line, then just by knowing one point and the slope you can graph the function because the slope will tell you how to get to the second point you need.\n\nFor instance, if you are told that a line goes through the point (0,2) and has a slope of 1/2 you can plot the second point and connect the dots to draw your line. Since the slope is "rise/run" you have to "rise" one and "run" two to get to another point. "Rising" 1 from 0 gets you to 1, and "running" 2 from 2 gets you to 4. So the next point is (1,4).\n\nIn a more general sense, the slope of a of a graph tells you how quickly the function is increasing or decreasing. For instance, the function f(x) = x^2 has a slope of 2x (trust me on this) where as the function g(x) = 2x^2 has a slope of 4x. What this means is that g(x) increases twice as quickly as f(x). If you look at these two lines on the same graph, it is evident that one increases much more quickly than the other.\n\nIf you progress on into higher mathematics courses, you will see how important the concept of the slope is, especially in Calculus.

y =mx + b\n\nFirst, the word linear will tell you this is the answer, as linear graph functions follow this format. From "best expressed", i got the hint that 4) is the answer cos its is the most direct relation. i.e. you plot in x and you get y, like a direct mirror.\n\n1) A quadratic equation will give you 2 solutions to a number you plot in, and from this itself, we can eliminate it. \n2) Complicated. The relationship isnt clear also, cos the entire thing seems to be pure gibberish\n3) This formula can only be applied in a right angled triangle. So it only shows ONE kind of relationship two variables can have.\n\nHope this helps=)

linear.  Linear means "to the first power", nonlinear means "to the second power (squared)", "to the third power" or higher (or some other function).  \n\nPerimeter of a square = 4 x length of side.\nwhich means \n4 x "length of side to the first power"\n\ndouble the length of the side and you double the perimeter; triple it and you triple the perimeter.

There will be a vertical asymptote at x=0. When x values get increasingly closer to zero from the right, the graph approaches infinity. When the x values approach 0 from the left, the graph approaches negative infinity.\n\nSimilarly, there is also a horizontal asymptote at y=4. As x approaches infinity, the graph approaches 4 (1/infinity + 4 = 4). Also, as x approaches negative infinity, the graph also approaches 4 (1/negative infinitive + 4 = 4).

A graph of many rates (rate of reaction, population growth, etc.) produce exponential curves (asymptotic).\nThese are difficult to interpret.\nTo linearise the curve plot log y against x, or log y against log x. The properties of the rate can now easily be established.\nHave a look here (note, second reference is PDF format):

I would say that linear thinking is like black and white.\nThere is "If_________ Then________ thinking.  Basically thinking 'within the box'.

That is an equation, but y is a linear function of x.

you have to look at the line a determine the slope. \nEx. look for a point where it is on the exact "cross shape" and start from 5 and go up the y-axes untill the point at the exact "cross shape" and the point where you stop on the y-axes" is parrallel to the x-axes. Now, go horizonally to the "exact-cross-shape point". Count how many you go up and how many you go across. Those counts will be your slope and if you go to the left then slope is negative and if you go to the right then the slope is positive.

i think it's a parabola.. im not sure. u should try plotting it on a graph.. substitute  the x and y values and see what form comes out..

I have no idea about the math, but I'm thinking the assumption is that the data are relatively correlated linearly.  There's a lot of math behind the wiki link.

When the whole equation is greater than zero, graph it like normal. When it's less than zero, graph it's negative. For example:\n\ny = /x + 1/\n\nWithout the absolute value signs, this would be positive when x > -1. So, for x >= -1, graph it like normal. For x < -1, graph -x - 1. You should get a v-shape, with only positive values.\n\nIf you have values added on outside the absolute value, then you just raise and lower the graph accordingly.\n\nAnd if you're still confused... try setting the expression equal to zero, and find x. Then, since it's linear, just plug in a value both less than and greater than this x to get two more points. Graph the three points, and connect with lines to get a v-shape.\n\nHope this helps!
