Question

What is the length of segment AB? (4 points)

A. 10
B. 12
C. 13
D. 15

Answer 1

(X1-X2)2+(y1-y2)2 use this formula to answer the question

Answer 2

C. 13

Explanation:

the line AB on the coordinate grid forms a triangle with the x and y coordinate lines

i used the Pythagorean Theorem

The line AB is the hypotenuse and the coordinate lines x and y are the legs

so here is my work:

c =
`\sqrt{a^(2) }+b^(2)`

c =
`\sqrt{12^(2) }+5^(2)`

c = 13

in conclusion, it's C. 13
