See a solution process below:

Explanation:

The formula to find the mid-point of a line segment give the two end points is:

M = ((color(red)(x_1) + color(blue)(x_2))/2 , (color(red)(y_1) + color(blue)(y_2))/2)

Where M is the midpoint and the given points are:

(color(red)((x_1, y_1))) and (color(blue)((x_2, y_2)))

Substituting the values from the points in the problem gives:

M = ((color(red)(-4) + color(blue)(0))/2 , (color(red)(0) + color(blue)(14))/2)

M = (-4/2 , 14/2)

M = (-2 , 7)

Difference between y values, difference between x values

Explanation:

Your function is starting point (-4, 0) and ending point is (0, 14)

Meaning change of x is from -4 to 0 (and half of it is -2)
Meaning change of y is from 0 to 14 (and half of it is 7)

Midpoint of your x is -2
Midpoint of your y is 7.
