Given it's midpoint and one endpoint apply the midpoint formula and solve for x and y midpoint (22,15) endpoint (18,6

Nutka1998 [239]

Midpoint formula

mid of (x1,y1) and (x2,y2) is
$( \frac{x2+x1}{2}, \frac{y2+y1}{2})$

so

(22,15)= $( \frac{18+x1}{2}, \frac{6+y1}{2})$
therefor

22= $\frac{18+x1}{2}$
and
15= $\frac{6+y1}{2}$

slv each
22= $\frac{18+x1}{2}$
times both sides by 2
44=18+x1
minus 18 both sides
26=x1

15= $\frac{6+y1}{2}$
times both sides by 2
30=6+y1
minus 6
24=y1

the other point is (26,24)

I don’t really get this.

Vsevolod [243]

Answer:

The answer is H. II and III only.

Step-by-step explanation:

A simple way to tell if a relation is a function is by taking a look at the X value, which is on the left. If the X value repeats again (ex: (0,1) (0,2) or (5,3 (5,7)) it is not a function. However, the Y value is allowed to repeat.
