Question

Match each set of ordered pairs with their rise over run.

Answer 1

(4,-2), (3,1) A.)-1
(4,-2), (-3,1) B.)-1/7
(-4,2), (-3,1) C.)-3
(-4,2), (3,1) D.)-3/7

Answer 2

@Mertsj

Answer 3

\[slope = \frac{ rise }{ run } = \frac{ y _{2}-y _{1} }{ x _{2}-x _{1} }\] when given the points (x1, y1) and (x2, y2)
so find the slope for each of the given coordinates and match them up.

Answer 4

so for example:
for the given points (4,-2) and (3,1)
let x1 = 4 , y1 = -2 , x2 = 3 , y2 = 1
and plug them into the
\[slope = \frac{ rise }{ run } = \frac{ y _{2}-y _{1} }{ x _{2}-x _{1} }\]

Answer 5

so for (4,-2) and (3,1)
\[slope = \frac{ (1)-(-2) }{ (3)-(4) }\]

Answer 6

you get -3

Answer 7

yep :) so that gives you your answer for that one.

Answer 8

WHAT ABOUT THE NEXT ONE?

Answer 9

and it's the same idea for the others
so for (4,-2) and (-3,1)
plug x1 = 4 , y1 = -2 , x2 = -3 , y2 = 1 so
\[slope = \frac{ rise }{ run } = \frac{ y _{2}-y _{1} }{ x _{2}-x _{1} } = \frac{ (1) - (-2) }{ (-3)-(4) }\]

Answer 10

d

Answer 11

yep :)

Answer 12

and for (-4,2), (-3,1)
plug x1 = -4 , y1 = 2 , x2 = -3 , y2 = 1
\[slope = \frac{ rise }{ run } = \frac{ y _{2}-y _{1} }{ x _{2}-x _{1} }\]

Answer 13

can you put in the numbers please

Answer 14

lol you should figure out how to do it yourself at some point :)
\[\frac{ (1) - (2) }{ (-3)-(-4) }\]

Answer 15

lol i got a

Answer 16

yep :)

Answer 17

Thanks

Answer 18

for (-4,2), (3,1)
plug in x1 = -4 , y1 = 2 , x2 = 3 , y2 = 1
\[slope = \frac{ rise }{ run } = \frac{ y _{2}-y _{1} }{ x _{2}-x _{1} } = \frac{ (1) - (2) }{ (3)-(-4) }\]
