Determine which of the following equations, when graphed, intersect at the point (4, 0). select all that apply. x - y = 4 -x - y = 4 2x - y = 7 x + y = 4 2x + y = 7 2x + y = -7

only (x-y=4) and (x+y=4).

Step-by-step explanation:

Notice target point has y=0, so all terms with y are zero. Then all 6 equations reduce to m x = k, for various m and k. So calculate 4×m and compare to k six times.

x - y = 4 4=4 yes

-x - y = 4 -4=4 no

2x - y = 7 8=7 no

x + y = 4 4=4 yes

2x + y = 7 8=7 no

2x + y = -7 8=-7 no.

answer: .75 km
