Answer:
, 
, 
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form
or 
Find the value of the constant of proportionality k
take any ordered pair from the data
For x=25, y=160

substitute the values of x and y

simplify

The linear equation is equal to

or

Y-y1=m(x-x1) is the point slope formula. m=3/4 and y1=-8 and x1=5. Substitute these values and you will have the answer.
