PLZ PLZ HELP! Medal Given!!! Finding slope...

OpenStudy (anonymous):

What is the slope of a line that passes through the pair of points (-5/3, -1), and (-2, 9/2)? a. 2/33 b. -2/33 c. -33/2 d. 33/2

jigglypuff314 (jigglypuff314):

\[slope = \frac{ rise }{ run } = \frac{ y _{2}-y _{1} }{ x _{2}-x _{1} }\]when given points (x1, y1) and (x2, y2)

OpenStudy (anonymous):

So it would be 9/2 - (-1) / (-2) - -5/3 ??

OpenStudy (isaiah.feynman):

Yes.

jigglypuff314 (jigglypuff314):

yep :) then simplify and be careful that - - = +

OpenStudy (anonymous):

So simplified wouldn't it be 5.5/-0.4?

OpenStudy (anonymous):

Because 9/2 turns into 4.5. And 4.5 - (-1) = 5.5. Then, -5/3 turns into -1.6. And -2 - (-1.6) = -0.4...

OpenStudy (anonymous):

I wasn't done! @jigglypuff314

jigglypuff314 (jigglypuff314):

sorry, I went to dinner. be careful to not round off too early -2 + (5/3) = -1/3 = -0.3333

jigglypuff314 (jigglypuff314):

I got a -16.5
