Question

What is the distance between R(1, -6) and S(10, 3)?
Round to the nearest tenth.

Answer 1

The distance formula for 2 points = √((x2-x1)^2 + (y2-y1)^2)

use R for x1 and y1 and use S for x2 and y2.

Distance = √((10- 1)^2 + (3-(-6))^2)

Distance = √(9^2 + 9^2)

Distance = √(81 + 81)

Distance = √162

Distance = 9√2

Distance = 12.7 ( Rounded to nearest tenth)
