Answer:

Red Line: y= 2x+5

Green Line: y= -2

Yellow Line: y= -3x+5

Black Line: y= 2x-6

Blue Line: x= 5

Explanation:

Slope Formula

m=y2-y1/x2-x1

m= slope

Red:

(0,5), (-3,-1)

5 - -1/ 0 - -3

6/3

m=2

y=2x+5

Green:

y=-2

Y value is always 0 no matter what x is equal to.

Yellow:

(0,5), (2, -1)

m= -1 -5/ 2-0

m= -6/2

m= -3

y= -3x+5

Black:

(2, -2), (5, 4)

m= 4- -2/ 5-2

m= 6/3

m= 2

y=mx+b

-2=(2)(2)+b

-2=4+b

-6=b

y=2x-6

Blue:

x=5

X is always 5 no matter what the y value is.
