Answer:
y=7x+5
Step-by-step explanation:
y-y1=m(x-x1)
y-(-9)=7(x-(-2))
y+9=7(x+2)
y+9=7x+14
y=7x+14-9
y=7x+5

This chart represents a proportional relationship. The rate of change will be 4.
<h3>What is the constant of proportionality?</h3>
Firstly, there is a proportional relationship.
Two values x and y are said to be in a proportional relationship if x=ky, where x and y are variables and k is a constant.
The constant k is called the constant of proportionality.
Given;
x y
1 4
2 8
3 12
4 16
Here, x = ky
put the first value
k = 1/4
This chart represents a proportional relationship.
So the rate of change will be
