Question

What is the equation of the line that passes through (1, 2) and is parallel to the line whose equation is 4x + y - 1 = 0?



4x - y - 6 = 0 or
4x + y - 6 = 0 or
4x + y + 6 = 0

Answer 1

Take the equation you're given and get it in y= form:
\[y=-4x+1\] The slope on this line is -4. To be parallel, two lines must have the same slope, so the answer will have -4 as the slope. We have a point on the line and the slope so we can plug into this formula:
\[y-y_1=m(x-x_1)\] so:
\[y-2=-4(x-1)\] Simplify this and we get our answer:
\[y=-4x+6\] And you can rearrange your answer choices to find the equivalent one.

Answer 2

it would be the first one right

Answer 3

im confused

Answer 4

u subtract y from both sides right

Answer 5

It would be the second one, subtract 4x and add 6 to both sides.

Answer 6

yea i had that the 1st time
