An architect needs to determine the slope between two points on a ski lift. The two points have been identified as (25, 30) and (125, 50), where x is the horizontal distance and y is the vertical distance from the bottom of the lift. Assuming the lift runs in a straight line, what is the slope of the line between the two points?

(Write your answer in simplest form, using / for a fraction bar if needed.)

My answer is 1.5

Am I right? :)

abb0t · Answer

$$slope = m = \frac{ y_2-y_1 }{ x_2-x_1 }$$
then, choose any of the two points and solve in the form y = mx+b
where you will be using: $$(y-y_1)=m(x-x_1) OR(y-y_2) = m(x-x_2)$$
