Question

Find the equation of the line parallel to the line x=3 and passing through the midpoint of the segment joining (9, 3)

and (5, -1).

Answer 1

x = 7

Explanation:

Midpoint:

x = (x1 + x2)/2 = (9 + 5)/2 = 14/2 = 7

y = (y1 + y2)/2 = (3 - 1)/2 = 2/2 = 1

If the line parallel to x = 3 so it should intersect x at 7

so x = 7
