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

(-1.5,3) Y=3 which is up 3 and a horizontal line and 2x+y=0 can be written as y=-2x so in order to get -1.5 you have to make y=3 cause y=3 and when you do that it should look like 3/-2=-2/-2x so x=-1.5

To get the answer, we need to substitute 3 for y in the equation 2x + y = 0.
2x + 3 = 0
2x = -3
x = -3/2

The answer is (-3/2, 3)
