Question

Find RT for R(-2, 5) and T(-3, -6).
Round to the nearest tenth.

Answers:
a) 8.5
b) 11.0
c) 9.8
d) 10.6

Answer 1

RT is the length of the line segment joining the points R and T.
Use the distance formula to find the distance between R and T.

Answer 2

The distance "d" between two points (x1, y1) and (x2, y2) is:
\[d = \sqrt{(x_2-x_1)^2 + (y_2-y_1)^2}\]
