Question

is this right?

Find the equation of a line given the point and slope below. Arrange your answer in the form y = mx + b, where b is the constant.

(5, 5)
m = -3

y=-3x+20

Answer 1

Again !:
Y2-y=m(X2-x)
5-y=-3(5-x)
5-y=-15+3x
-y=-20+3x
y=20-3x
And right .

Answer 2

this is how i did....

y-5=-3(x-5)
y-5=-3x+15
add 5 0n both sides
y=-3x+20????????????????????
