Question

The slope of the line below is -2. Which of the following is the point-slope form of the line?
(4,-8)

Answer 1

is it y - 8 = -2(x + 4) orr....

Answer 2

Point Slope form is written as (y - y1) = m ( x-x1)

m = slope and (x1, y1) is the point given to you.

So the slope here is -2 and point is (4,-8)

Now ( y - y1) will be (y-(-8)) = ?

Answer 3

Thanks(:

Answer 4

Similarly (x-x1) = (x - 4)

Answer 5

So you got it?

Answer 6

I think so is it y + 8 = -2(x - 4)?

Answer 7

yes

Answer 8

Thanks again:D
