Find the equation of the line with slope 2 and y-intercept (0,−1).

2x-y = 1

Step-by-step explanation:

Equation of the line is y-y1 = m (x-x1), where m is the slope and (x1,y1) is a point that lies on the line.

Equation of the given line is,

y-(-1) = 2 *(x-0)

y+1 = 2x

2x-y = 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).
