The value of r in the given coordinates with their slope is; r = 7
How to find the Slope of a Line?
The formula for slope of a line passing through 2 points is;
m = (y2 - y1)/(x2 - x1)
We are given the coordinates as;
(1,-10) and (r,2)
The slope of the line passing through this coordinates is 2. Thus;
(2 + 10)/(r - 1) = 2
12 = 2r - 2
2r = 14
r = 14/2
r = 7

Answer:
11.81
Step-by-step explanation:
5 1/4 per 20 min (1/3 of an hour)
5.25 (5 1/4) * 3 = 15.75 pounds per hour
$0.75 earned per pound
So, 15.75 * $0.75 = $11.81
We need to solve the speed formula for d. To do so, let's start by moving the number of the left hand side:

Square both sides to get rid of the square root:

Now plug the known value of the speed to find the distance:

So the closest answer is the last one: d=0.155km
