Answer:
-4
Step-by-step explanation:
From (-1,1) to (0,-3) is a fall of 4 and a run of 1
therefore rise over run = -4/1 = -4
Slope Formula
-4
Hope this helps,
Answer:
Part A: y = 4.5x + 22
Part B: 31 inches
Step-by-step explanation:
Part A:
the y-intercept appear to be at 22
the slope can be found by using the points (0, 22) and (4, 39)
m = <u>39 - 22</u>
4 - 0
m = 17 / 4 = 4.3 and this is close to 4.5
Part B:
plug in 2 for 'x' in the equation: y = 4.5x + 22
y = 4.5(2) + 22
y = 9 + 22
y = 31
