The slope of a line describes how steep a line is. Slope is the change in y values divided by the change in x values. Use the graph below to find the slope of the line that goes through the points (1,2)left parenthesis, 1, comma, 2, right parenthesis and (6,6)left parenthesis, 6, comma, 6, right parenthesis.

The Slope of a Line. The slope of a line is how steep the line is and whether the line is an uphill or a downhill. Slopes can be whole numbers or fractions and either positive or negative.

Finding the Slope Check the box labeled "Display Equation on Chart" and then close the window. Examine the equation for the line, which Excel is now displaying overlaid on the scatter plot. The equation will be in the form of "y = mx + b" where m and b will be numbers. The value of "m" is the slope of the graph.

To find the slope, find the difference between the two y values and divide it by the difference between the two x values. The midpoint is obtained by taking the average of the two x values and the average of the two y values.

To find the slope of a line given the equation of the line, first write it in slope-intercept form. Use inverse operations to solve for y so that it is written as y=mx+b. Then you can easily see the slope since it is the coefficient of the x variable, or the number in front of x.

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).

To find the slope of an equation given in y=mx+b, balance the equation until y is by itself without any constants. First subtract 8 from both sides to get 4y = 6x + 10. Next, divide the equation by the constant 4 to isolate y, giving you y = 3/2x + 5/2.

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.

The slope equals the rise divided by the run: Slope =riserun Slope = rise run . You can determine the slope of a line from its graph by looking at the rise and run.

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 know the slope (m) any y-intercept (b) of a line, this page will show you how to find the equation of the line.

To determine the slope of a line passing through two points, we need to know the coordinates of 2 points on the line. Then the slope of the line is given by the quotient of the difference between the y-coordinates and the difference between the x-coordinates. i.e. slope = (y2 - y1) / (x2 - x1).

Use the slope formula to find the slope of a line given the coordinates of two points on the line. The slope formula is m=(y2-y1)/(x2-x1), or the change in the y values over the change in the x values. The coordinates of the first point represent x1 and y1.
