Step 2 Substitute the slope for m in the slope intercept form of the equation. The horizontal line has a zero slope while the vertical. If 1 Point and the Slope are Known.
Determine the rise between the two points.
Learn how to find the slope between two points. To solve the problems in this lesson students use the slope formula which states that m y2 - y1 x2 - x1. Step 1 Calculate the slope from 2 points. The slope of a line is the steepness of the line.
