Question

Determine the slope of (a) every line that is parallel to the given line and (b) every given line: x=-1/2y+3

Answer 1

to start, solve the equation for y.

Answer 2

I have y=5x-4/2

Answer 3

x can be dependant on y :)

Answer 4

that is wrong. just do the basic algebra to get everything from the right side to the left until y is the only thing left on the right side.

Answer 5

y = -2x - 3/2.....maybe

Answer 6

No matter what way I do it, I still end up getting the same thing

Answer 7

so your original equation first becomes x-3 = -1/2y

Answer 8

then you multiply both sides by -2

Answer 9

so you get y=-2x+6

Answer 10

I appreciate it very much. I just do not see where you multiply both sides by -2

Answer 11

I am just confused.

Answer 12

well you're trying to get rid of the -1/2 on the right side. to do this, you can multiply by -2. but remember that what you do to one side, you have to do to the other.

Answer 13

OKay, now that I understand. Thank you so much.

Answer 14

no problem. and from that new equation, you should be able to see the slope fairly easily. if not, look through your notes/textbook.

Answer 15

my voices in me head lied to me!! 3/2 ok, which one of you did it....
