$3.75 would be rounded up and changed to $4
I dont think the answer is always. Because integers are always whole numbers. Hope that helps a little?

Answer:
Step-by-step explanation:
<u>Midpoint of JK:</u>
- x = (-12 + 8)/2 = -4/2 = -2
- y = (3 - 5)/2 = -2/2 = -1
<u>Slope of the line JK:</u>
- m = (-5 - 3)/(8 - (-12)) = -8/20 = -2/5
Perpendicular lines have negative reciprocal slopes.
So the line r has a slope 5/2 and passes through the point (-2, -1)
<u>Equation of r:</u>
- y = 5/2x + b
- -1 = 5/2(-2) + b
- -1 = -5 + b
- b = 5 - 1
- b = 4
<u>So the equation is:</u>
You need to know the distance travelled to work that out???
