Question

Find the line parallel to y=-4x-1 going through (1,-3)

Answer 1

You would use the same equation given keeping the same slope (y=-4x+b) and replace x and y with the coordinate (1,-3) to solve for b. After that you plug in b into the equation to get the answer.

Answer 2

So basically your answer would be y=-4x+1

Answer 3

Where do i plug B into?

Answer 4

A linear equation is y=mx+b

Answer 5

m equals slope and b is the y intercept

Answer 6

Yes i know that

Answer 7

Do you get it?

Answer 8

Where di you get the slope?

Answer 9

Oh wait

Answer 10

Never mind...

Answer 11

First you would find the slope of the first equation, which is y = -4x-1
After you find the slope, the second line has to have the same slope as the first line.
Use the equation y=mx + b, and solve for b. For x and y, plug in (1, -3)

Answer 12

It says you are looking for a parallel line, there fore the slope must be congruent

Answer 13

Both equations have to have the same slopes

Answer 14

-3=-4(1)-1

Answer 15

^ I plugged it in

Answer 16

The slope of the first line is -4.
y = mx + b
-3 = -4(1) + b
-3 = -4 + b
b = 1.
Plug in b = 1 to the equation y = mx + b, where m = -4.
y = -4x + 1

Answer 17

I get it! Thanks dude! <3
