Using the Slope Equation Pick two points on the line and determine their coordinates. Determine the difference in y-coordinates of these two points (rise). Determine the difference in x-coordinates for these two points (run). Divide the difference in y-coordinates by the difference in x-coordinates (rise/run or 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.

Equation of a Straight Line. Equations of straight lines are in the form y = mx + c (m and c are numbers). m is the gradient of the line and c is the y-intercept (where the graph crosses the y-axis).

How to Use the Formula and Calculate Slope. The slope of a line characterizes the direction of a line. To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points .

You can't find the slope of a line if only given one point. If you had a visual representation of the line such as a graph or a table you could find a second point and then use the formula for slope, y = (y2-y1) / (x2-x1). Imagine a single point on the xy graph.

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.

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.

Slope is the 'steepness' of the line, also commonly known as rise over run. We can calculate slope by dividing the change in the y-value between two points over the change in the x-value.

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.

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.
