Question

(2,-3) perpendicular to y=4x+7

Answer 1

perpendicular means what about the slope?

Answer 2

opposite reciprocal

Answer 3

exactly...so use the equation
(y-y1)=m(x-x1)
plug the point they give you into (x1,y1) and the perpendicular slope in for m

Answer 4

y=-1/4x-15/6? that's my answer

Answer 5

wow thanks so much.. can you help me with more? its confusing because its perpendicular to a vertical line

Answer 6

(2,1) perpen to x=-2

Answer 7

sure :D

Answer 8

you use the same equation..

Answer 9

y=1/2x?

Answer 10

wow!

Answer 11

5,-2 parallel to x=4.. is the answer x=5?

Answer 12

CONGRATS! i think you have the hang of it. Just remember the rule of perpendicular slope and the distributive property :D

Answer 13

try this one on your own.

Answer 14

how would I find the slope if its undefined?

Answer 15

what do you mean? why is it undefined?

Answer 16

slope for x=anything is always undefined

Answer 17

exactly..so whats the opposite of undefined?

Answer 18

this one is parallel not perpendicular

Answer 19

yupp your answer is correct :D

Answer 20

thanks so much for help!!
