find 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
I 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
I 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
