Answer:
D(0,5)
Step-by-step explanation:
for me I first had to mark the points on a graph then I connected the dots I know then point C I had to connect straight down to x (0) and it made a right angle. I hope that helps make sure to ask me more questions I'm free to help
Answer:
D(-7,-2)
Step-by-step explanation:
Formula for midpoint:
[tex]Midpoint=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]
It is given that the midpoint of CD is E (–1, 0) and the coordinates of C are (5,2).
Let the coordinates of other endpoint are (a,b), then coordinates of E are
[tex]E=(\frac{5+a}{2},\frac{2+b}{2})[/tex]
It is given that the coordinates of E are (–1, 0).
[tex](-1,0)=(\frac{5+a}{2},\frac{2+b}{2})[/tex]
On comparing both sides we get
[tex]\frac{5+a}{2}=-1[/tex]
[tex]5+a=-2[/tex]
[tex]a=-2-5[/tex]
[tex]a=-7[/tex]
The value of a is -7.
[tex]\frac{2+b}{2}=0[/tex]
[tex]2+b=0[/tex]
[tex]b=-2[/tex]
The value of b is -2.
Therefore the coordinates of the other endpoint are D(-7,-2).
