THE CORRECT ANSWER WILL GET BRANLIEST

Answer:

k=11

Step-by-step explanation:

Slope is calculated by dividing the change in y over the change in x.  The change in x for these points is 4.  This leaves us with y/4 as the slope, which must equal 2.  Divide both sides of the equation (y/4=2) by 4.  y=8

Now add 8 to the y coordinate of (1,3) in order to get a y value of 11 for the second coordinate.
