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

A box is 50 cm long. Which of these is closest to the length of this box in feet? (1 inch = 2.54 cm)
goblinko [34]

First, convert cm to inches.

50/2.54 is roughly 19.69

There are 12 inches in a foot, so divide the 19.69 by 12.

19.69/12 is roughly 1.64

So the answer is C
