# Math Help - How can I solve these equations by graphing?

1. ## How can I solve these equations by graphing?

y=-3x+4
x+y=2

And the second question

y=x+1
y=-x+3

I'll do the first, you do the second.

You want to graph the line
$y = -3x + 4$

and graph
$x + y = 2$
in other words:
$y = -x + 2$

The intersection point of the two graphs is your answer.
