Can someone help me with Writing equations of lines

y=-1/5x-1

Step-by-step explanation:

given two points (10, -3) and (5, -2) y intercept at -1

There are different ways. One of them:

Slope: -2-(-3)/5-10=-1/5

y=mx+b

m-slope -1/5

b y-intercept (-1)

y=-1/5x-1

(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).

hope i
