Question

Solve the following system of equations by graphing.

x + 2y = 8
x + 2y = -4

What is the solution?

(3, 5)

no solution

infinite solutions

none of the above

Answer 1

I have x=4 and y=0 but since my answer isn't up there what should i pick then?

Answer 2

would it not be none of the above then?

Answer 3

how did u get x=4 and y=0 ?

Answer 4

although you may have solved it wrong.

Answer 5

that's another possibility.

Answer 6

x=4, y=0 satisfy none of the given equations, so thats not the solution

Answer 7

actually,

Ax+By = C1
Ax+By = C2

lines are parallel; they never intersect; no solutions.
