Midpoint of (a,b,c) and (e,f,g) is
((a+e)/2,(b+f)/2,(c+g)/2)
just average them
the x value
(2+-2)/2=0/2=0
the y value
(-2+0)/2=-2/2=-1
the z value
(4+6)/2=10/2=5
(0,-1,5) is da midopint
Answer:
y=-3x+1
Step-by-step explanation:
plug in point into x and y, replace -4 as a +b(or any other variable to represent y intercept)
therefore,
7=-3(-2)+b
7=6+b
1=b
y=-3x+1
Answer:
The correct answer is x= - 3
