The scatterplot and regression line below show the average income, in dollars, in several major American
cities plotted against the rent for a 2-bedroom apartment in those cities.

step-by-step explanation:

see if this :

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation

slope =   (y2 -y1) ÷ (x2 -x1)

slope = (0 -0) / (-5, -7)

slope = 0 / -12 = 0

the slope of the line is zero.   it is perfectly horizontal.
