Question

help please
Find the equation of the line that passes through the points (2,8) and (-5,10)

Answer 1

Find the slope (first x minus first y)/(second x minus second y). Then, just put that and one point into point slope form and viola!

Answer 2

ok i am doing it just a minute

Answer 3

i got -3.5

Answer 4

That is your slope. You still have to put it into point slope form, along with either point you wish, to get your equation.

Answer 5

is point slope for y=mx+b

Answer 6

is point slope form y=mx+b?

Answer 7

ok is the answer y-8=-3.5(x-2)

Answer 8

I believe so yes. If your teacher or whoever is picky, they may want you to put everything on one side in standard for, but that looks good.

Answer 9

\[y-y1=\frac{ y2-y1 }{ x2-x1 }\left( x-x1 \right)\]
