Question

Ac has endpoints a=(-2,3) and c=(10,9). what would be the y cordinate of point b that bisects ac

Answer 1

hello

point A = -2, 3

Point B = 10, 9

to solve this problem, we'll use formula of mid-point

`x,y=(x_2+x_1)/(2),(y_2+y_1)/(2)`
`\begin{gathered} x_1=-2 \\ x_2=10 \\ y_2=9 \\ y_1=3 \end{gathered}`
`\begin{gathered} x=(x_2+x_1)/(2) \\ x=(10+(-2))/(2)=(8)/(2)=4 \end{gathered}`
`\begin{gathered} y=(y_2+y_1)/(2) \\ y=(9-3)/(2)=(6)/(2)=3 \end{gathered}`

the mid-point is 4, 3

the coordinate of point b is (4, 3)do
