Slope-intercept form formula:

For this formula we need the slope to find the slope use the slope formula:

Plug in the two points (1,-3) and (3,1)

=2
the slope is 2
Now use the slope-interpect formula and plug in the slope (m)

plug in one point I'll use (3,1)

1 = 6 +b
1-6=6-6+b
-5 = b
The equation would be:
