Sally works in a cell phone store. She is paid a weekly salary of $80 plus $5.25 for each cell phone she sells. Which equation can be used to find Sally’s total weekly
income?

First, let's define some variables.

x = # of cell phones sold.

y = total weekly income.

y = $5.25x + $80

Another way is

If $80 is her standard income per week, then there is no variation in how much she's earning for that chunk of money. The phones however are $5.25 per phone shes sold, and that exact number could vary, so we’d represent that with “x.” the correct equation to solve this would be y(total weekly income)= $5.25x + 80

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.
