\text{Distance } = √( (x_2 -x_1)^2 + (y_2 - y_1)^2)

You are given -9 and -3, which can also be written as (-9,0) and (-3,0) respectively.

Plugging those two points into the formula, you get:


√( \left(-3 - -9\right)^2 + \left(0 - 0\right)^2)\\ √( \left(-3 + 9\right)^2 + \left(0 + 0 \right)^2)\\√(\left( 6\right)^2 + 0)\\√( 36 )\\ √( 36 ) \approx\boxed{ \bf{6}}

So the distance between -9 and -3 is 6.

Remember the distance between two numbers, or points, is always going to be positive.
