Question

the slope of the line is -2. find the point slope equation of the line.
(4,-6)

is it y - 6 = -2(x+4) ?

Answer 1

y-(-6)=-2(x-4)

Answer 2

The points are plugged in correctly, but the signs are wrong. Since its y-y1, the double negative would become a +. And the +4 would actually be a -4 because of the x-x1.

Answer 3

It would then be: y+6 = -2 (x-4)

Answer 4

Remember

-*-=+

+*-=-

+*+=+

-*+=-
