If you draw a vertical line from the terminal point (-3,-4) to the x axis, you'll land at (-3,0). A right triangle forms with the right angle on the x axis.
This triangle has legs of 3 and 4. The hypotenuse is 5. We can see this if we solve for x below
a^2+b^2 = c^2
3^2+4^2 = c^2
c^2 = 25
c = sqrt(25)
c = 5
So the length of segment 'a' is 5 units.
The final answer is choice D) 5
