Question

The slope of the line below is -1. Write the point-slope equation of the line using the coordinates of the labeled point. (7,-7)

Answer 1

(y-y1)=m(x-x1)

Answer 2

slope means gradient
grd=-1 (x,y) (7,-7)
\[change \in y \]----------\[change \in x\]y--7/x-7
y+7/x-7=-1
cross multiply
y+7=-x+7
y=-x-7+7
y=-x

Answer 3

gimmie a answer!

Answer 4

y=-x
