Answer:
D
Step-by-step explanation:
y-y1=m(x-x1) through (4,4)
x-3y= -18 is perpendicular : m1*m2=-1
y=mx+c
-3y=-18-x
3y= 18+x
y=x/3 + 6
y= 1/3x + 6
m1*m2= -1
m1= -1/m2
m1= -1/1/3
m1= -3
y- 4= -3(x - 4)
y-4= -3x +12
y= -3x +12+4
y= -3x + 16
The distance between the two is 10
True-... i think because like i am not sure-
The mean would be 4.5. This is because you add up all the numbers which equals 22.5. Then divide by 5 since there is 5 numbers in the set. So the answer comes out to be 4.5.
