You have $50 dollars in your savings account. each week you deposit $5 in your account. write an expression that models the situation. is this relationship proportional or non-porportional ? how do you know?

Hey there!

Let's write our expression below.

5x+50

A proportional relationship can be written in the form y=kx, so let's rewrite our expression as an equation.

y=5x+50

A proportional relationship must pass through the origin. The y-intercept has to be 0. y=5x would be proportional, but we have y=5x+50, so therefore it is not proportional.

I hope this helps!
