An architect needs to determine the slope between two points on a ski lift. The two points have been identified as (15, 35) and (195, 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.)

Hey do u know how to calculate slpe from two points (x1,y1) and (x2,y2) ?
Not really
Do u multiply?
\[\frac{ y2-y1 }{x2-x1 }\] is the slope
did i delete your comment @dmezzullo if i did, im sry that was by mistake
ur fine
i did
I still dont kno wut to do?!?!?!
tell us whats ur problem
wut u mean wuts my problem?
Slope: Rise over run. Or... Change in y over change in x. Your two points were (15 , 35) and (195 , 50) RISE: Your two y-values are 35 and 50. What's the difference? (Assuming it's FROM 35 TO 50)
i still dont get this one bit sorry guys.
(15, 35) and (195, 50) has the same slope as (15/5, 35/5) and (195/5, 50/5) (3, 7) and (39, 10) -3-7 -3-7 ---------------- 0,0 36,3 id say its about 3/36

ok
|dw:1363792235356:dw| What's the difference between the y-values? (ie by how much did it increase? )
Oh i see now, u divide by a number that can go into all of them then subtract the smaller values.
^yeah, but there's still no avoiding the formula for slope: \[\huge \frac{y_2-y_1}{x_2-x_1}\]
15 is the difference
That's right :) so your "rise" is 15 What's your "run" ? Run is the difference in the x-values, this time.
:) working with smaller numbers tends to be preferential to most
THe other difference is 180 isnt it?
That's right :) Rise = 15 Run = 180 Slope = Rise over run Go for it, champ ;)
