Answer:
y = x + 2
Explanation:
Use any two points.
For example, let's use (-3, -1) and (1, 3).
First, we find the slope.
slope = m = (-1 - 3)/(-3 - 1) = -4/(-4) = 1
We have slope = m = 1.
Now we use the equation:
y = mx + b
We plug in the slope we found above.
y = 1x + b
y = x + b
Now we use one of the given points to find b.
We'll use point (1, 3).
3 = 1 + b
b = 2
Now that we know m and b, we write the equation:
y = x + 2
