Question

Which of the following is the equation of a line parallel to the line y = 4x + 1, passing through the point (5,1)?

Answer 1

is it 4x+y=-19?

Answer 2

You must first use the point (5, 1) for x and y, and then 4 for m as the slope as parallel lines will have equivalent slopes.

1 = 4(5) + b

Solve for b to get the y-intercept

1 = 20 + b

-19 = b

Answer 3

So y = 4x - 19 is the equation.

Answer 4

it has to be in standard form

Answer 5

Rearrange in that case to ax+by+c = 0

Answer 6

4x - y - 19 = 0

Answer 7

so, in Ax+By=C, it would be 4x-y=19?

Answer 8

Correct!

thanks a lot! :D
