Answer:
Option D
Step-by-step explanation:
From the picture attached,
If each block of the graph is a square with the dimension of 1 unit,
Measure of leg 1 = 5 units
Measure of leg 2 = 12 units
By applying Pythagoras theorem in the right triangle given in the picture,
(Hypotenuse)²= (leg 1)² + (leg 2)²
(Hypotenuse)²= (5)² + (12)²
(Hypotenuse)²= 25 + 144
Hypotenuse = √169
Hypotenuse = 13
Therefore, length of the given line will be 13.
Option D is the answer.
