Answers for the points (3,2) and (–1,–1).
The rise is 3
.
The run is 4
.
The slope of the line is 3/4
.
Step by step
Slope is found using
y2 - y1 over x2-x1
-1 - 2 over -1 -3
-3 (rise) over -4 (run)
y/x is slope so
3/4 is the slope
You can find the equation using
y - y1 = m (x - x1) using one set of points (3,2)
y - 2 = 3/4 (x - 3)
y - 2 = 3/4x - 2.25
y -2 +2 = 3/4x -2.25 + 2
y = 3/4x - .25
