Y =1/3x - 1 so slope = 1/3
if <span>perpendicular, slope = -3
passing thru (4,-2) then
y = mx +b
-2=-3(-2) + b
-2=6+b
-2-6 = b
so b = -8
equation:
y = -3x - 8</span>
Answer:
Midpoint (-2,4)
distance nearest tenth = 8.9
The approximate distance = 9
Step-by-step explanation:
Formulas
PQ midpoint = (x2 + x1)/2, (y2 + y1)/2
distance d = sqrt( (x2 - x1)^2 + (y2 - y1)^2 )
Givens
x2 = -4
x1 = 0
y2 = 1
y1 = 7
Solution
M(PQ) = (-4+0)/2, (1 + 7)/2
M(PQ) = -2, 4
The midpoint is -2,4
The distance = sqrt( (4 - 0)^2 + (1 + 7)^2 )
The distance = sqrt(16 + 64)
The distance = sqrt(80)
The distance = 4√5 exactly
The distance = 8.94
The distance = 8.9 To the nearest tenth
Question 2
The distance is rounded to the nearest whole number which is 9.
Hello!
The answer for #1. is 4 centimeters, because it is the only reasonable answer.
The answer for #2. is 1 millimeter, because the tick is smaller than the penny, which is smaller than any of the other lengths.
I hope this helped :))
