Answer 3

go and download geoegebra its a free graphing package.

or the alternate method is to get some graph paper find the intercepts for each line, then graph the line

to find the x- intercepts (where the line cute the x axis) let y = zero and solve for x

for your 1st line if y = 0

2x +2*0 = -6 or 2x = -6 then x = -3

for y-interscepts let x = 0 and solve for y

2*0 + 2y = -6 2y = -6

you can finish...

If you know where a line cuts the x and y axes you can draw the line.

repeat the process for the other line...

and your point if intersection will be obvious.

Answer 4

Graph each equation and see where they intersect.

Answer 5

solve for y then paste what you got for y in google seperated by commas

2x + 2y = –6, 3x – 2y = 11

Answer 6

is it b? @timo86m

Answer 7

x = 1, y = -4

Answer 8

so yes you are right :D

Answer 9

Yes, you got it right.
