If M is the midpoint of segment RS, then
M = (R + S)/2
2M = R + S . . . . . multiply by 2
S = 2M - R = 2(8, -2) -(10, 5) = (6, -9) . . . . put in the given values
6y- 12x =24
6y= 24+12x
y=4+2x
Answer:
The answer is 7
Step-by-step explanation:
There are two ways:
One if you have a graphing calculator (TI-84 plus) you can go to stat then edit then type in the -40 and -90 on the left and the -120 and 60 on the right. The press stat again and go to the right to calc the down to linreg (ax +b) and go down to calculate amd press enter.
Your answer is y = -3.6x+-264
option two is by hand
the formula is y1-y2 divided by x1-x2
R=( 432/12)* 1/2= 36* 1/2= 18
R= 18
