The answer is 7.68.
Hope this helps.
Given:


To find:
The sum of m and n.
Solution:
We have,


The sum of m and n is:

Combining the like terms, we get



Therefore, the sum of m and n is
.
General form of the line equation is: y= mx + c
where m is the slope and c is the constant
the slope here is given and equal to 3
so, m= 3
y= 3x +c
to get the constant c, substitute with the point in this equation
y= -2 & x = 1
-2 = 3*1 + c
c = -5
then the equation of the line is y = 3x -5
y = 3x -3 -2
y +2 = 3(x-1)
the answer is (B)
