Question

An architect needs to determine the slope between two points on a ski lift. The two points have been identified as (15, 45) and (150, 60), 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?

Help please?

Answer 1

Do you know the slope formula?

Answer 2

Yes, I do. It's y=mx+b

Answer 3

That is the slope-intercept form of a linear equation.
The slope formula is y2-y1 over x2-x1


Subtract the y values. Subtract the x values. Make a fraction with the first number on top.

Answer 4

So in this case: 60-45/150-15 or 15/135 = 1/9 and that is the slope

Answer 5

Oh.

Answer 6

Do you understand?

Answer 7

Not really...
