Question

Determine co-ordinates of the mid point of a line segment with endpoints at: L(12,8) and M(18,2)

Answer 1

Step-by-step explanation:

the formula for the mid point is:

{(x1 + x2)/2 , (y1 + y2)/2}

so using the formula we get:

(15, 5)

also are you sure that the question wants the midpoint? since the answer is not included in the choices

Answer 2

Answer:

C(15,3)

Step-by-step explanation:

Midpoint = $\frac{x_{1}+x_{2} }{2}, \frac{y_{1}+y_{2} }{2}$

               = $\frac{12_{}+18_{} }{2}, \frac{8_{}+2_{} }{2}$

               = 15,5 (which is closest to C, i think there is a mistake in the        question as there is only one formula to find midpoint so y coordinate has to be 5)
