As part of the proof, find the midpoint of xy

d. (a, -2b)

step-by-step explanation:

for points x(x1, y1) and y(x2, y2), the coordinates of the midpoint are m( (x1 + x2)/2, (y1 + y2)/2 ).

in this case, the points are x(2a, 0) and y(0, -4b).

the midpoint is:

m( (2a + 0)/2, (0 + (-4b))/2 ) =

= m( 2a/2, -4b/2)

= m(a, -2b)

answer;

the correct answer

just use google you beautiful person.

have a nice day < 3

answer: a.

step-by-step explanation: the answer is a. because, you need to converge the fractions to find a solution.
