Answer:
y = 2.25x
Step-By-Step Explanation:
If I divide y by x, in any of the tables, it is always 2.25.
y ÷ x = 2.25
Then, I can multiply x on both sides to make the equation showing the proportional relationship.
y ÷ x × x = 2.25 × x
y = 2.25x

Answer:
y=25x+50
Step-by-step explanation:
The rental rate for a power washer has a one time fee of $50 plus $25 for each day of the rental.
let x be day of rental n y be the total cost of rental
with 0 day (x=0), the one time fee means y=50 which is the y-intercept
$25 per day means the slope is 25
combining y = 25x + 50
