What is the midpoint of EF If E has the coordinates of (2,4) and F has coordinates of (6,8)

allsm [11]

Answer:

$\boxed {\boxed {\sf (4,6) }}$

Step-by-step explanation:

The midpoint formula is:

$(\frac{{x}_{1}+{x}_{2}}{2},\frac{{y}_{1}+{y}_{2}}{2} )$

where (x₁, y₁) and (x₂, y₂) are the points are the endpoints.

We are given the points: (2,4) and (6,8). Therefore,

$x_1=2\\y_1=4 \\x_2=6 \\y_2=8$

Substitute the values into the formula.

$(\frac{2+6}{2},\frac{4+8}{2})$

Find the x coordinate first.

Add 2 and 6: 2+6=8
Divide by 2: 8/2=4

$(4, \frac{4+8}{2})$

Find the y-coordinate next.

Add 4 and 8: 4+8= 12
Divide by 2: 12/2=6

$(4,6)$

The midpoint of EF is (4,6)
