Solve the system of equations by substitution. Show your work in the sketch and write your answer as an ordered pair. There are 2 sketches in case you need more room.

`-3x+y=-2`

`y=4x`

Let's solve your system by substitution.

−3x+y=−2;y=4x

Rewrite equations:

y=4x;−3x+y=−2

Step: Solvey=4xfor y:

y=4x

Step: Substitute4xforyin−3x+y=−2:

−3x+y=−2

−3x+4x=−2

x=−2(Simplify both sides of the equation)

Step: Substitute−2forxiny=4x:

y=4x

y=(4)(−2)

y=−8(Simplify both sides of the equation)

x=−2 and y=−8

slope is 35 and 20 miles is the y-intercept.
