A line /ell passes through the points B (7,-1) and C(-1,7). The equation of this line can be written in the form y=mx+b compute m+b.
+179 m= -1, b = 6, m+b = 5
If you would like to know my method, reply to this and I can take time to explain. Basically though, just plug the ordered pairs into the equation and solve the system.
