Question

Solve each system by graphing.
4. y = -4x
y = - x + 6

(0, 6)
(-6, 6)
(-2, 8)
(-8, 0)

Answer 1

do you know how to draw the first line: the best way is to plug in some values: for example y=-4x surely goes through the point (0,0) which is origin because when you plug in x=0 you get y=0...now you try to plug in any other value for x and find value for y can you try?

Answer 2

from both equations,

-4x = -x + 6

solve this and get 'x'. What do you get?
