Answer: Slope = 3
Function: y = 3x+6
Explanation:
Gather 2 points.
(-1, 3), (-3, -3)
Divide: (y1 - y2) / (x1 - x2)
-3 -3 =-6
-3 -(-1) = -2
-6/-2 = 3
Slope is 3 (m = 3)
Point-Slop Intercept:
(y - y1) = m(x - x1)
y-(-3) = 3(x-(-3))
(two negatives = Postive) Distribute the slope to the numbers inside parenthesis:
y-(-3) = 3x + 9
y + 3 = 3x + 9
Subtract 3 from both sides
y = 3x + 6.
