What is the distance in units between the points (8,-1) and (-2,-1) on a coordinate plane?
1 answer:
You can use the distance formula.
The distance formula says the distance between two given points (x1, y1) and (x2, y2)
=
Your given points are (8, -1) and (-2, -1).
The distance will be
.
But you could have recognized that both points have the same y-coordinate of -1, which means change in distance is determined by change in x-coordinates only.
Change in x-coordinates is |-8 - 2| = 10. There is absolute value because distance cannot be negative.

Answer:
Step-by-step explanation:
We are given the vertices of triangle ABC. We need to find the length of median AD.
Please see the attachment for figure.
D is mid point of BC because median bisect the opposite side of triangle.
Using the formula of mid point. we get coodrinate of D
D is mid point of B(1,5) and C(-3,-1)
AD is median of triangle ABC. Now we find length of median AD using distance formula of two coordinate.
A(5,1) and D(-1,2)
Thus,
