Center:(0,0), r=13
(x-center)^2+(y-center)^2=r^2
x^2+y^2=13^2
x^2+y^2=169
Points include: (13,0) and (0,13) among many more

Answer:
3 steps
Step-by-step explanation:
FIrst of all, if you think about it, we can just say -3 as 3 ( even though they are not equal, were just counting steps.)
On a number line, negative numbers are on the left of 0 and positive on the right of 0.
So, lets say the middle number is 0 on our number line. -3 is 3 steps to the left. We take 1 step to negative 1, another step to -2, and then a 3rd and final step to -3.
The steps represent how far the number is from 0. FIr example, we have to add 3 to -3 to get to 0, like how we add 7 to 0 to get 7!
Hope this helps!
