Answer:
(x y) = (1 2/3, 4 2/3)
Step-by-step explanation:
We're not sure the basis you're intended to use for estimating. Perhaps you're given a graph, or are intended to draw a graph. The attachment from a graphing calculator is able to tell us what the point of intersection is.
(x, y) = (1 2/3, 4 2/3)
__
The only "estimate" we need to make is that 0.667 ≈ 2/3.

Answer:
Step-by-step explanation:
The distance (d) between two points in 3 dimensions is ...
d = √((x2 -x1)² +(y2 -y1)² +(z2 -z1)²)
Then the distance between (a, -b, -4) and (0, 0, 0) is ...
d = √((a -0)² +(-b -0)² +(-4 -0)²)
= √(a² +b² +16)
