Question

Find the approximate length of segment GH on the graph.

Answer 1

You could use the distance formula, but another way is the Pythagorean theorem.

3² + 5² = c²
9 + 25 = c²
34 = c²
c = 5.83
Rounded = c = 6

Answer 2

On the y-axis segment GH starts at 2 and goes to 5. Therefore using 5-2 you get 3, the length of GH
