Answer:
A. (3, 8) and [tex]2\sqrt{2}[/tex]
B. (2, 4) and [tex]2\sqrt{10}[/tex]
Step-by-step explanation:
Midpoint formula: [tex](\frac{x1+x2}{2} ,\frac{y1+y2}{2})[/tex]
Distance formula: [tex]\sqrt{(x_{2}-x_{1}) ^2+(y_{2}-y_{1}) ^2 }[/tex]
A. plug in the points in the formulas
(4, 7) and (2, 9)
Midpoint:
[tex](\frac{4 + 2}{2} , \frac{7+9}{2} )=6/2, 16/2 = (3,8)[/tex]
Length:
[tex]\sqrt{(2-4)^2+(9-7)^2}=\sqrt{4+4} =\sqrt{8} =2\sqrt{2}[/tex]
B.
(5, 5) and (-1, 3)
Midpoint:
[tex](\frac{5-1}{2} , \frac{5+3}{2} )=4/2,8/2=(2,4)[/tex]
Length:
[tex]\sqrt{(-1-5)^2+(3-5)^2} =\sqrt{-6^2+-2^2} =\sqrt{36+4} =\sqrt{40} = 2\sqrt{10}[/tex]
Can you consider marking my answers as brainliest lol it would mean a lot. Hope this helped.
