What is the vertical change from Point A to Point B? 1

What is the horizontal change from Point A to Point B? 2

What is the rate of change shown on the graph? Give

the answer as a decimal rounded to the nearest tenth.

if necessary: 0.5

Step-by-step explanation:

The rate of change, as the own name suggest, is the rate at which the function change its value. The function, in this case is changing with a rate of 0.5 because to each unit that x grows, y grows the half part of it.

answer: i'm going in

step-by-step explanation:

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
