Question

How do i solve x+y=8 and y-x=2 so i can graph them?

Answer 1

they are perp lines.

Answer 2

y = -x +8 and y = x+2

Answer 3

you can plot them after that

Answer 4

if im correct my paper is asking for the x and y intercept

Answer 5

\[x+y=8\] x intercept is (8,0) and y intercept is (0,8)

Answer 6

\[x-y=2\] x intercept is (2,0) and y -intercept is (0,-2)

Answer 7

now how do i come to that?
iwant to learn how to do it

Answer 8

The x intercept is where the x value is 0, so plug 0 in for x and solve for y
And vice versa for the y intercept
