Two points I can assuming to have integer coordinates (points without decimals in (x, y) ) are (0, 0) and (5, 40)
From this, I can make a safe assumption that y is 8 times the x value.
since x value is money spent on advertising in $1000s', number of vehicles is 80 times of how much money is spent on advertising in $1000.
But, if you want to be fancy (or I guess this is more correct), 8/1000 = 0.08, so for extra dollar spent, 0.08 more vehicles are sold, rounded down.
Step-by-step explanation:
Given
Perimeter of square (P) = 64 cm
first calculating the length
P = 4L
64 = 4L
L = 64 / 4
Therefore L = 16 cm
Now Finally Calculating Area
Area of square
=L²
= (16)²
= 256 cm²
Hope it helps :)

Sorry for what happened but the equation is a bit hard so
I think the answer is y=-2x+6
Hypotenuse² = perpendicular² + base²
H² = 20²+21²
H²= 400+441 = 841
H = √841
H = 29 cm
