Question

If the two lines 2x + y = 0 and y = 3 are plotted on a typical xy coordinate grid, at which point will they intersect?

Answer 1

(3/2,3) will be the intersection. Y= -3 and then you plug in -3 for y in the equation so then it will be 2x -3 =0. Then add three to both sides of the equation so now it will be 2x=3 divide both sides by two which would be x=3/2.
