The standard form of a line: .
The point-slope form:
We have the point (3, -1) and the slope m = -1. Substitute:
<em>add x to both sides</em>
<em>subtract 1 from both sides</em>

Answer:
r = 1
Step-by-step explanation:
slope = change in y / change in x, so:
change in y / change in x = 2/3
5 - r / 7 - 1 = 2/3
5 - r / 6 = 2/3
now solve this equation.
first, multiply both sides by 6 to get rid of the fraction:
subtract 5 from both sides
multiply both sides by -1
