Answer:
Step-by-step explanation:
P(1, -2) ;Q(4,3)
Let R(x1,y1)
Midpoint=[tex](\frac{x_{1}+x_{2}}{2},\frac{y_1+y_2}{2})\\[/tex] = (4,3)
[tex](\frac{1+x_1}{2},\frac{-2+y_1}{2})=(4,3)\\[/tex]
Compare x coordinates and y coordinates
[tex]\frac{1+x_1}{2}=4 ; \frac{-2+y_2}{2}=3[/tex]
1+x1 = 4*2 ; -2+y2 = 3*2
1+x1 = 8 ; -2 +y2 = 6
x1= 8-1 ; y2 = 6+2
x1 = 7 ; y2 = 8
R(7 , 8)
