Find the coordinates of the midpoint: (4,4) (4, -18)

(4 , -7)

Step-by-step explanation:

Formula for finding the co-ordinate of the mid point through section formula :-

where (x' , y') are the co-ordinates of the mid-point of the line segment whose co-ordinate points of ends of the line segment are  (x¹ , y¹) & (x² , y²) .

In the question ,

x¹ = 4

y¹ = 4

x² = 4

y² = - 18

Using the values above in the formula ,

a: 1/6, j: 1/4
