Question

What would be the graphing points of the system of equations? also please explain
y=-2x-2
y=2x-2

Answer 1

you can make any points graphing points by subbing in a number for x and solving for y

y = -2x - 2 ....lets make x = 1
y = -2(1) - 2
y = -2 - 2
y = -4
so when x = 1, y = -4....thus (1,-4)

and do it like that till you have several points....for both lines. Now the solution for this system is when the two lines intersect.

OR...
you can find the x and y intercepts of each line.
x int can be found by subbing in 0 for y and solving for x
y int can be found by subbing in 0 for x and solving for y

Answer 2

okay thank you, i understand it better now. i think i was just making it too complicated.
