Can someone please help me with this ?

y intercept=15 and slope is 3

Step-by-step explanation:

Ok so for this one we know the y intercept is 15 because the y intercept is wherever x=0 and in the table when x=0 y=15

to find slope we use (y2-y1)/(x2-x1) which when we put points (0,15) and (1,18) in for would be:

(18-15)/(1-0)

3/1

= 3

step-by-step explanation:

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).
