Question

I Need guidance.

Choose the equation of the line passing through the point (-4, -2) and parallel to y = 1 fourthx + 2
I don't know how to start this problem at all. I need help and guidance

Answer 1

Anyone? :/

Answer 2

look at your equation : y = 1/4x + 2...can you tell me the slope of this equation ?

Answer 3

\[Y=\frac{ 1}{ 4}x+2\]

Answer 4

1/4 right?

Answer 5

correct..it is 1/4....and a parallel line will have the same slope.

now we use y = mx + b
we already know slope(m) = 1/4
(-4,-2)....x = -4 and y = -2
now we just need to find the y intercept, which is b
now sub

y = mx + b
-2 = 1/4(-4) + b
-2 = -1 + b
-2 + 1 = b
-1 = b

so your parallel equation is : y = 1/4x - 1
any questions ?

Answer 6

Ohhhh !! I Got it now Thank you sooo much.

Answer 7

do not get this confused with perpendicular lines...there a little different

Answer 8

So all your doing is plugging in the numbers right?

Answer 9

yep...and solving for b, the y intercept

Answer 10

Okayy Thanks

Answer 11

sure thing :)
