Question

given: M(-4,-1), B(-5,-3) find the midpoint

Answer 1

$\bf \textit{middle point of 2 points }\\ \quad \\ \begin{array}{lllll} &x_1&y_1&x_2&y_2\\ % (a,b) M&({{ -4}}\quad ,&{{ -1}})\quad % (c,d) B&({{ -5}}\quad ,&{{ -3}}) \end{array}\qquad % coordinates of midpoint \left(\cfrac{{{ x_2}} + {{ x_1}}}{2}\quad ,\quad \cfrac{{{ y_2}} + {{ y_1}}}{2} \right) \\\\\\ \left(\cfrac{{{ -5}}-4}{2}\quad ,\quad \cfrac{-3-1}{2} \right)$

Answer 2

midpoint formula : (x1 + x2) / 2 , (y1 + y2) / 2
(-4,-1).....x1 = -4 and y1 = -1
(-5,-3)....x2 = -5 and y2 = -3
now we sub
m = (-4 - 5) / 2 , (-1 - 3) / 2
m = (-9/2 , -4/2)
m = (-9/2 , -2) <===
