Answer:
y = (1/3)x - (1/3)
(1/3)
Explanation:
We can find the slope by subtracting Q points by P points.
(2 - (-1)) / (7 - (-2))
3 / 9
1/3 = slope
To find y intercept we can use the slope and find the difference left
y = (1/3)x
-1 = (1/3)(-2)
-1 = -(2/3)
This is not true
To make it true we must subtract -(1/3)
This means our equation is
y = (1/3)x - (1/3)
