please help me on this. These two eqautions when graphed are parralell to each other i believe. But im not sure how to calculate the difference in vertical and horizontal. please help!!!! a.s.a.p.!!

Answer 1

Graph them. You will find that the vertical distance between them is 7. (One crosses the y axis at 3 and the other at -4). Along a horizontal line (such as y = 0), the spacing of the lines will be the distance from x = -3/2 to x = 2, which is 3 1/2.
