Idont understand how to solve this problem
parallel to y=3/2+4 and through (2,-3)

Parallel means it must have the same slope so assuming you meant y=3/2x+4 the slope will remain 3/2

Then you just plug in the coordinates they give you

-3=(3/2)(2)+b
-3=3+b

b=-6 (b is the y intercept)

Final y=3/2x-6

Aperecent is the answer
