Solve the equation 5 m + 4 m equals 72

For this case we must look for the value of the variable "m" of the following given equation:

Adding similar terms we have:

Dividing between 9 on both sides of the equation:

Thus, the value of variable m is 8

The point-slope equation is y-k = m(x-h), where m is the slope and (h,k) is the point.

Subbing the given info into y-k = m(x-h), we get:   y+2 = (1/3)(x+2)
