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?

This is how I did it :
y2-y1
------
x2-x1


x1=15
x2=150
y1=45
y2=60

60-45
------
150-15

15

135

which simplifies to 9 . Right ?

Answer 1

1/

Answer 2

15/135
1/9

Answer 3

1/9 ?

Answer 4

yep

Answer 5

Yes.

Answer 6

I thought you just did 135/15 which gave me 9 .
