Write an equation of the line in slope-intercept form which passes through (-2,0) and is perpendicular to a line whose equation is y=-3x+7

keeping in mind that perpendicular lines have negative reciprocal slopes, let's find what's the slope of y=-3x+7 anyway, wait just a second! y=-3x+7 is already in slope-intercept form .

and since that's the slope of that equation, a perpendicular line's will be

so we're really looking for the equation of a line whose slope is 1/3 and runs through -2,0,

(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).
