Answer 1

hmm what graph?

Answer 2

Shouldn't you solve this system first..

Answer 3

x + y = 4
2x + 3y = 18

x=4-y
2(4-y)+3y=18
8-2y+3y=18
y=10

x=4-y
x=4-10
x=-6

Answer 4

so how do i know which graph presents that information? I'm learning this.

Answer 5

Do you know how to plot?

Answer 6

y=10
x=-6
Find these points on a graph, draw a line connecting them

Answer 7

ohhhh okay got it!!!! thanks!
