One easy way of finding this is using the slope formula. y2-y1 / x2-x1 = m \[\frac{ -7-3 }{ -2-0 }\]

OpenStudy (anonymous):

first find the slope of the first line.

OpenStudy (secret-ninja):

So you get \[\frac{ -10 }{ -2 }\] And you simpluify and get \[-\frac{ 5 }{ 1 }\]

OpenStudy (anonymous):

do that by using @Secret-Ninja 's formula. then you find the oposite reciprocal of the slope.

5

OpenStudy (secret-ninja):

Do you understand? @muycool

OpenStudy (anonymous):

no, it would be c

OpenStudy (anonymous):

it was B

OpenStudy (anonymous):

but thanks anyway

OpenStudy (secret-ninja):

>.< Woah wut

OpenStudy (anonymous):

since the oposite reciprocal of -1/5 is 5, you would get C, not A.

OpenStudy (secret-ninja):

Sorry, I had a brain fart. :/

OpenStudy (anonymous):

wait, B???
