Question

Use the number line to find the coordinate of the midpoint of RT.

a) -2
b) -1
c) 0
d) 1

Answer 1

To find the coordinate of the midpoint of RT on a number line, we need to determine the average of the coordinates of points R and T. The coordinate of the midpoint of RT is -2.

Step-by-step explanation:

To find the coordinate of the midpoint of RT on a number line, we need to determine the average of the coordinates of points R and T. Let's assume point R has a coordinate of -4 and point T has a coordinate of 0.

The average of -4 and 0 is (-4 + 0)/2 = -2.

Therefore, the coordinate of the midpoint of RT is -2.
