Question

The equation of line CD is y = −2x − 2. Write an equation of a line parallel to line CD in slope-intercept form that contains point (4, 5).

Answer 1

y=-2x has to start like this to be parallel (same slope)

Can you figure out the rest of the equation?

Answer 2

wats sup

Answer 3

Not much. At work... boring rainy day

Answer 4

same here... ummm i believe you have to replace the y with 4, so 4=2x

Answer 5

so im thinking divide 4/-2, which equals -2

Answer 6

(4, 5). this point has to satisfy the equation
x is first, y second

Answer 7

ohhh yea, so do you divide the 5/-2?

Answer 8

y = −2x + or - something will be the solution
at (4, 5)
5=-2*4
5=-8 so the - or + something is??

Answer 9

-3 must equal b then

Answer 10

so the final answer could be y=-2x-3

Answer 11

5=-8 -3 =-11
Still nope
5=-8 +-?

Answer 12

5=-8 +-?
Instead of +-? you can write lets say z
5=-8 +z z=?

Answer 13

where did the -11 from

Answer 14

im sorry come from

Answer 15

You wrote -3
-8-3=-11 that is not 5

Answer 16

y=-2x-3 this line does not contain (4,5) as
5=-8-3=-11 not cool

Answer 17

ok, so what i did was take the 5 and subtract 8 from it, which is -3=b since you solve for b and i was just thinking that you could not change the slope

Answer 18

i honestly dont know where to go with this

Answer 19

5=-8 + b
Lets use b than :)
Solve the above!

Answer 20

i got -27=b

Answer 21

because you plug in the 4 right?

Answer 22

No :( Sorry

Answer 23

5=-8 + b
Add 8 to both sides
5+8=-8+8+b
13=b

Answer 24

wow, i found my mistake now

Answer 25

i had to add 8 to both sides. Thanks man, sorry for my incompetence

Answer 26

Oh that is nice :) It is always the best way to learn something

Answer 27

No probs :)
In a few years you will get there
