The midpoint of the line segment A(2a,4) & B(-2, 3b)is C(1,2a+1) .find the values a & b. |
| Answer» Since the point C is midpoint of AB , Ratio=1:1So, applying the section formulax =x1+x2/21=2a-2/2. a=2 Same case with y y=y1+y2/22a+1 = 4-3b / 2 Put value of a solved above2(2)+1=4-3b/210-4 = -3bb= -2 | |
