when a linear function is graphed it passes through the points (-1,1), (1,5), and (3,9) what is the rate of change for the funct
ion?
1 answer:
Use the linear slope formula to solve for m:
m=(y2-y1)/(x2-x1)
using the points (-1,1) and (1,5) you can find the slope for the first interval:
m=(5-1)/(1-(-1))
m=4/2
m=2
you can double check by using the same formula on the second interval, which is (1,5) to (3,9).
m=(9-5)/(3-1)
m=4/2
m=2
therefore, the rate of change is 2.

It would be: 11 * 90/100
= 11 * 0.90 = 9.9
So, your final answer is 9.9

Answer:
x = 45/8
Step-by-step explanation:
8x – 3y = 36
Let y=3
8x – 3*3 = 36
8x - 9 = 36
Add 9 to each side
8x -9+9 = 36+9
8x = 45
Divide each side by 8
8x/8 = 45/8
x = 45/8
12 because if u had 3 groups of 4 that would be 3+3+3+3
