Question

Find the point-slope equation for

the line that passes through the
points (9,-9) and (-2,13). Use the
first point in your equation.
y + [? ] = [ ](x+[ ])

Answer 1

Answer: y-[9] = -[2](x-[9])

Step-by-step explanation: Hope this helps :)

Answer 2

The answer to your question is y = -2x + 9

Explanation:

A (9, 9)

B (-2, 13)

Process

1.- Find the slope

m =
`(y2 - y1)/(x2 - x1)`

`m = (13 + 9)/(-2 - 9)`

`m = (22)/(-11)`

m = - 2

2.- Find the line equation

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

y + 9 = -2 (x - 9) y + ? = [ ] ( x + [ ])

y + 9 = - 2x + 18

y = - 2x + 18 - 9

y = -2x + 9
