Answer:
y = 2x - 5
Explanation:
slope = 1-(-3)/3-1
4/2 = 2
this is the m value, or value before x.
So far, this is what we have: y = 2x + b
To find b, we plug in one of the points we have, into the equation.
(in this case ill use (3, 1), where 3 is the x and 1 is the y)
So,
1 = 2(3) + b
1 = 6 + b
1 - 6 = b
-5 = b
Finally,
y = 2x - 5
