The equation of the relationship y = 10x + 10 and it is not a proportional equation
How to determine the equation of the relationship
From the question, we have the following parameters that can be used in our computation:
x 0,1,2,3
y 10,20,30,40
A linear relationship is represented as
y = mx + c
Where
c = y when x = 0
So, we have
y = mx + 10
Using the points, we have
m + 10 = 20
m = 10
This means that
y = 10x + 10
Hence, the equation is y = 10x + 10
