The value of m is the slope of the graph. To write an equation in slope-intercept form given a graph of that equation pick two points on the line and use them to find the slope. This is the place on your graph where the line will cross over Step 2 Draw your graph.
In a straight line equation which is formed by using Slope and Intercept where Slope is ratio of rise and run which are there anywhere in the straight line.
The SLOPE function in Excel is used to calculate the slope of a line given known x and y values. Zero is a number. The value of m is the slope of the graph. This is the place on your graph where the line will cross over Step 2 Draw your graph.
