**Reiny**, Thursday, October 7, 2010 at 7:20pmfind the slope , call it m

write it as

y = mx + b

use one of the points to replace the x and y values, that way you can find b

put that back in, and you are done

let me know what you get

**Hannah**, Thursday, October 7, 2010 at 7:30pmI got y=-10/3 x + b

Then I used (-5,4) so 4=-10/3(-5) + b

and I got y=-10/3x - 46/3. I am not sure if I multiplied and added the fractions correctly

**Reiny**, Thursday, October 7, 2010 at 7:36pmI had b = -38/3

a trick is to use the point that was not used and sub it is, the other point does work for -38/3
