In which quadrant on the coordinate plane is (-a - 3, 2b - 5), if a = - 4 and b = - 5?

- a - 3 = x

Plug in - 4 for a

= - ( - 4) - 3

= 4 - 3

= 1

2b - 5

Plug in - 5 for b

= 2 (-5) - 5

= - 10 - 5

= - 15

So (-a - 3, 2b - 5) = (1, - 15)

Notice 1 is positive and - 15 is negative.

This means (1,-15) is in the second quadrant.
