How do you solve linear equations?
!

Step-by-step explanation:

First step is to isolate "x" to one side of the equation by adding 2y to both sides:

Second step is to divide both sides by 2  

The you can check your work with the original equation.

Hope that helps:)

parallel and congruent

step-by-step explanation:

the movement of translation is linear.   these have the same translation because you are using the same rule for each point of the triangle so you will see the same slope being used to get from a point on the triangle to its image.

same slope!   you should think parallel when you see those 2 word together (well unless it's the same line but it can't be because we are coming from different points here)

congruent! because each point is being moved the same distance.

x equals 1

step-by-step explanation:

f(4)=f(×)

x=1
