The equation of the line that passes through the points $(-3,5)$ and $(0,-4)$ can be expressed in the form $y=mx+b$. What is the value of $m+b$?

The line is y = -10/3*x - 5, so m + b = -10/3 - 5 = -25/3.

That is not correct. Thank you though.

Slope of  the line =  (-4 - 5)  / ( 0 - - 3)  =  -9 / 3  = -3

 

Using the point  (0, -4)   we  have  that

 

y = -3(x - 0)  - 4

 

y =  -3x   -  4

 

m +  b =    -3  +  (-4)   =    -7
