Answer 6

point and slope form is (y-y1)=m(x-x1) + c, where m is slope n c is a constant.

so u got x1, y1 and m already; just need to solve for c

Answer 7

Y-1/2=-x+1/2 ??

Answer 8

y+1/2=-x-1/2

Answer 9

Wait wait im sorry....i think i made a mistake.....

Answer 10

or y+1/2=-x+1/2

Answer 11

point and slope form is (y-y1)=m(x-x1) so u got it already :)

Answer 12

sorry about my mistake @RobertoTB

Answer 13

so which one is it

Answer 14

@superdavesuper

Answer 15

(y-y1)=m(x-x1) and just put in x1, y1 and m

Answer 16

y-1/2=-x-1/2

Answer 17
