<u>The Equation of a Line</u>
The equation of the line in slope-intercept form is:

Where m is the slope and b the y-intercept.
The equation of a line passing through points (x1,y1) and (x2,y2) can be found as follows:

We are given the points (5,2) and (0,-1), thus:

Operating:


To find the slope-intercept form, we continue to simplify the expression:
Removing the parentheses:
