Question

write the slope-intercept form of the equation of the line described:
through: (2,-1) parallel to y=-2x+2

Answer 1

i know that the slope will be the same, since it's parallel.. i just am not sure as to how to find the y-intercept

Answer 2

\[y-(-1)=-2(x-2)\]\[y=-2x+4-1\]\[y=-2x+3\]

Answer 3

is the formula: y-y1=M(x-x1)?

Answer 4

???

Answer 5

for point-intercept, yes. it is.

Answer 6

okay, thanks. you mind helping me with perpindicular real fast?

Answer 7

sure.

Answer 8

okay thanks.
it says: through: (-5,2) perp. to y=-5/3x+1

Answer 9

anyone??

Answer 10

perp means that it's slope is the negative rec. of your other given slope, so plug in the new point and slope, and solve.

Answer 11

so my slope is now 3/5?

Answer 12

yep.

Answer 13

okay hold on

Answer 14

is 3/5x+1 correct?

Answer 15

no, the slope is correct, but the y-int isn't.

Answer 16

okay i seee my mistake

Answer 17

y=3/5x+4 ?

Answer 18

still nope

Answer 19

what's the answer?
