3x+y=9

2x+y=8

The graphing method

3x + y = 9 ⇒ 6x + 2y = 18

2x + y = 8 ⇒ 6x + 3y = 24

-1y = - 6

-1 - 1

y = 6

3x + 6 = 9

-6 - 6

3x = 3

3 3

x = 1

(x, y) = (1, 6)

No thats standard form. to graph it you need to turn it into slope-intercept form which is y=mx+b where m is the slope (rise over run) and b is the y intercept.

for example to get it for 3x+y=9 you would take away the 3x and put it on the other side.

3x+y=9

-3x - 3x and that would become:

y = - 3x+9

thats graphing method.
