Write an equation in point-slope form that describes the line with a slope of -3 that contains the point (1,2)

Step-by-step explanation:

The point-slope form of equation of function passing the point (x₀,y₀) where m is the slope  is:  y - y₀ = m(x - x₀)  

m = -3

(1, 2)     ⇒    x₀ = 1,    y₀ = 2

y - 2 = -3(x - 1)

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150
