Answer 1

What is the x-coordinate of point B?

Answer 2

negative 5

Answer 3

Correct.
What is the x-coordinate of point O?

Answer 4

-1.5 i think

Answer 5

Correct.
Since the segment OB lies in a horizontal line, just subtract -1.5 from -5 and take the absolute value to find the length of OB

Answer 6

Or you can just look in the graph to find the distance between -1.5 and -5 on the x-axis.

Answer 7

but my choices absolute value x+5/2 , x-3/2, x-5/2, x+3/2
