slope of y= -1+3x is "3"

of y=-x+7 is "-1"

of y=3x+8 is "3"

i) y intercept = "-9"

ii) y intercept = "-2"

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get
