Question

Q # 18 Find the midpoint of. A B

Answer 1

Point A lies on the x-axis and distance from point A to the y-axis is 2 units, then the coordinates of A are (-2,0) (-2, because A lies on the left side from the origin and 0 because A lies on x-axis).
The distances from point B to the x-axis and y-axis are 2 and 4, then tha coordinates of point B are (4,2).
To find the middle-point M of segment AB you should use formulas:
`x_M= (x_A+x_B)/(2) \\ y_M= (y_A+y_B)/(2)`.
Then
`x_M= (-2+4)/(2)=1 \\ y_M= (0+2)/(2)=1`.
Answer: M(1,1), correct choice is C.
