Question

Solve by graphing:
3x-2y=6
x-y=2

Answer 1

(Systems of equations xD)

Answer 2

Do I have to change the 2 equations into slope intercept form?

Answer 3

It would be best if you did

Answer 4

okay, so then...

Answer 5

solve for y in the 2nd equattion
y = x-2
and plug into first one
and solve for x
after you get that plug the x value into y=x-2 to get the y value

Answer 6

okay...

Answer 7

x=2

Answer 8

yea thats right

Answer 9

But then it's solve by graphing...so don't I have to graph to find the coordinates to solve it?

Answer 10

y=0

Answer 11

oh sorry you can graph both of them
solve for y on both equations
you should have 2 equation in this form y=mx+b
b = intercept and m = slope

the answer is when the 2 graphs intersect

Answer 12

wait...but I got this random point smack in a middle of the box.

Answer 13

So...how do I know what it is?

Answer 14

hm.. thats odd it should intersect at (2,0)
let me try it

y= 3/2x -3
y=x-2
