Question

Solve the system by graphing.
y=-2x+2
5x+y=5

Answer 1

substitute the value of the first equation into second one.

Answer 2

5x+(-2x+2) = 5

Solve, you will get a value for x.

Answer 3

y = -2x+2
y = 5-5x

y = y

-2x+2 = 5-5x

3x = 3
x =1
y =0

Answer 4

now how do i go about graphing it? is it only one point

Answer 5

Yes, I gave you the way to graph them by solving both for y

Answer 6

oh ok thanks

Answer 7

Notice the y equals

Answer 8

You will see that they intersect at the point (1,0)

Answer 9

for the first one,

-2 is the slope and 2 is the y intercept.

Answer 10

yes y=y. so the point is (1,0) and just graph that

Answer 11

Using a graphing calculator would be a good idea

Answer 12

I dont have one that is the problem lol

Answer 13

I'm sorry to hear that

Answer 14

its ok
