see explanation.

#### Explanation:

From the origin, move 8 units to the left along the

This is the point (-8 ,3)

Since there is a right triangle formed from

#0to-8to3to0# we can use Pythagoras' theorem to calculate it's magnitude, which is the distance from the origin to the point (-8 ,3)

#rArrsqrt(8^2+3^2)=sqrt73larr" absolute value"#
