Question 3 of 25 What is g(x)?​

Carla is on the right track because she is finding the slopes of consecutive sides to check for right angles.

Step-by-step explanation:

The slope of the line passing through the points and is

Find the slope of the line passing through the points C(2, 3) and D(1, 2):

Find the slope of the line passing through the points D(1,2) and E(4,1):

These slopes have the product

so angle D is not a right angle.

Carla is on the right track because she is finding the slopes of consecutive sides to check for right angles.
