Question

Write an equation in point-slope form of the line through point J(4, –4) with slope 4.

Answer 1

\[Y-Y1 = m(X-X1)\]

Answer 2

That's point-slope form, where (X1.Y1) is the given point.

Answer 3

so y-4=4x+4 ?

Answer 4

Err no try again.
Also, 'm' is the slope of the line.
Also don't forget youur Y value is actually negative.

Answer 5

or y+4=4x-4

Answer 6

Eh, almost. You got the left part right. This is what the right should look like:
4(x-4)
You have to distribute the 4 to each component.

Answer 7

-4(x-4) ?

Answer 8

Err, no lol.
We're keeping 4(x-4)
But you have to distribute the 4 to each term.
4(x-4) = 4*x - 4*4 = 4x - 16.

y + 4 = 4x - 16

Answer 9

well that's not any of my choices

Answer 10

Ehh, what are your choices? o.o

Answer 11

You have to reduce it to slope-intercept form, perhaps?
Which means getting y by itself?

Answer 12

a. y+4=4(x+4)
b. y+4=4(x-4)
c. y-4=4(x+4)
d. y+4=-4(x-4)

Answer 13

Oh yeah, it's B.

y + 4 = 4(x-4)

Answer 14

Das what I showed you. :3

Answer 15

@Jack1

Answer 16

Um...ok.

Answer 17

i'm stuck between b and c can you help

Answer 18

that was for jack btw

Answer 19

I said it was B! Point (4,-4) , slope of 4
(y-y1) = m(x-x1)
(y+4) = 4(x-4)

Answer 20

hey shay, bun's helpin u out here, bear with him

Answer 21

but you were confusing me taking me all around the world at first

Answer 22

Sorry. I was just showing you how to do it.

Answer 24

Ohhh, you didn't put parentheses around your original answer. That's why :o

Answer 25

ok
