Question

What is the equation in standard form of a parallel line that passes through (0,-2)? The line parallel to (0,-2) is y=-4x+4

Answer 1

Try using the same process I showed you, except using the fact that parallel lines have identical slopes.

Answer 2

Point-Slope form --> y = mx + b --> move mx to the left

Answer 3

\[y+2=-4(x-0)\]

Answer 4

-4 being the slope cause of the y=-4x+4

Answer 5

that's right, now to y = mx + b form

Answer 6

\[y=-4x+2\]

Answer 7

Careful, you subtracted 2 from the left side, so you should subtract from the right as well.

Answer 8

But I did subtract... ? from \[y+2=-4(x-0)\] \[y=-4x+2\]

Answer 9

\[y + 2 = -4x\]\[y + 2 - 2 = -4x - 2\]

Answer 10

Oh right I forgot about the 0..

Answer 11

\[y+2-2=-4x-2\] \[y=-4x-2\] \[4x+y=-2\]?

Answer 12

$$4x + y = -2$$ is correct :-)

Answer 13

Thanks you two!

Answer 14

Thanks for asking.
