Choose the equation of the line passing through the point (-1, 7) and perpendicular to y = - 1/4 x - 5.

OpenStudy (sparklestaraa):

2 in one @misty1212

OpenStudy (misty1212):

perpendicular what is the slope of the line perpendicular to a line with slope \(-\frac{1}{4}\)?

OpenStudy (misty1212):

if you don't know tell me

OpenStudy (sparklestaraa):

i really don't know

OpenStudy (sparklestaraa):

im guessing 0/4

OpenStudy (misty1212):

lol no it is the "negative reciprocal" flip it and change the sign you get \(4\)

OpenStudy (misty1212):

0/4 = 0 that is wrong

OpenStudy (sparklestaraa):

-4?

OpenStudy (sparklestaraa):

this just got confusing xD

OpenStudy (misty1212):

no dear not -4, just plain old 4

OpenStudy (sparklestaraa):

so y=4x+11?

OpenStudy (misty1212):

oui

OpenStudy (misty1212):

\[\color\magenta\heartsuit\]

OpenStudy (misty1212):

next one is real similar

OpenStudy (sparklestaraa):

is the next one C? @misty1212

OpenStudy (misty1212):

idk

OpenStudy (misty1212):

no because the slope should be 3, not 7
