what is the equation of a line with slope?
433930
The equation of a line is typically written as y=mx+b where m is the slope and b is the y-intercept. If you a point that a line passes through, and its slope, this page will show you how to find the equation of the line.

['The slant of a line is called the slope. Slope describes how steep a line is. ... ', 'For example: Given two points, P = (0, –1) and Q = (4,1), on the line we can calculate the slope of the line.', 'For example: Consider the two points, R(–2, 3) and S(0, –1) on the line. What would be the slope of the line?']

' When the 'rise' is zero, then the line is horizontal, or flat, and the slope of the line is zero. Put simply, a zero slope is perfectly flat in the horizontal direction. The equation of a line with zero slope will not have an x in it. It will look like 'y = something.

The slope equation says that the slope of a line is found by determining the amount of rise of the line between any two points divided by the amount of run of the line between the same two points. ... Divide the difference in y-coordinates by the difference in x-coordinates (rise/run or slope).

The slope m of a line is one of the elements in the equation of a line when written in the "slope and intercept" form: y = mx+b. The m in the equation is the slope of the line described here. For more on this see: Intercept of a line.

The basic equation of the line is y = mx + b, where m represents the slope of the line and b is the y-intercept. For this question we simply plug in the values for the appropriate variables to get the correct equation of the line.

Slope describes the steepness of a line. The slope of any line remains constant along the line. The slope can also tell you information about the direction of the line on the coordinate plane. Slope can be calculated either by looking at the graph of a line or by using the coordinates of any two points on a line.

PROOF: The equation for slope is y1−yx1−x . If the equation is x=−2 , we can substitute this value into y1−yx1−x to get y1−y−2−(−2) , and simplifying this equation makes the denominator 0 , which is undefined.

This is the slope of the line (usually called m). If you need to find the equation of the line simply input all of our knowns into the slope/line formula: y-y1=m(x-x1). For the above example that's y-1=1(x-2). Then simplify and you've got y=x-1.

The coordinates of every point on the line will solve the equation if you substitute them in the equation for x and y. The equation of any straight line, called a linear equation, can be written as: y = mx + b, where m is the slope of the line and b is the y-intercept.

If you know the slope m , and y -intercept (0,b) of a line (the point where the line crosses the y -axis), you can write the equation of the line in slope-intercept form .

In mathematical terms, the slope is the rate of change of y with respect to x. When dealing with linear equations, we can easily identify the slope of the line represented by the equation by putting the equation in slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept.

In the equation of a straight line (when the equation is written as "y = mx + b"), the slope is the number "m" that is multiplied on the x, and "b" is the y-intercept (that is, the point where the line crosses the vertical y-axis). This useful form of the line equation is sensibly named the "slope-intercept form".

To calculate the slope of a line you need only two points from that line, (x1, y1) and (x2, y2). The equation used to calculate the slope from two points is: On a graph, this can be represented as: There are three steps in calculating the slope of a straight line when you are not given its equation.
