Question

through: (4,-4), parallel to y=-x-4

Answer 1

Your going to have to use point slope form here. Which is y-y1= m(x-x1)

Answer 2

not necessarily...you can use y = mx + b form...you just need to know the slope

Answer 3

You have the point (4,-4) and m=-1
When you plug the points in you would have y -(-4) = -1(x - 4)
two negatives make a positive so y +4 = -1(x - 4)
Next you distribute the -1 to (x-4) and you would get y +4 = -x + 4
Then you subtract the 4 from the right side of the equation and subtract it from the left and you would get y=-x

Answer 4

Well we do know the slope so we are just trying to find an equation that would be parallel to the original @texaschic101

Answer 5

we do...but does the asker know how to find the slope

Answer 6

The slope is in front of X

Answer 7

y = mx + b

The m=slope and b=y - intercept

Answer 8

you are correct in that the slope is -1. And parallel lines will have the same slope

y = mx + b
slope(m) = -1
(4,-4)....x = 4 and y = -4
now we sub...we are looking for b, the y intercept, since we already know the slope is -1.

y = mx + b
-4 = -1(4) + b
-4 = -4 + b
0 = b

so basically your parallel equation is : y = -1x + 0...or just y = -x

Answer 9

Thats what i just said...

Answer 10

yes..I did not say yours was wrong. All I said is that you can use the slope intercept formula....or you can use point slope formula (your suggestion). Either answer should come out the same.

Answer 11

What ever lol this is easy peasy will you help me with the question i posted? @texaschic101
