10-151.

Find the distance between the two points.

$\left(x, y\right)$ and $\left(−3, y\right)$
Step 1(a):
Notice that the y values are the same. (the line is horizontal)
Step 2(a):
Just subtract −3 from x to find the distance.
Answer (a):
x + 3

$\left(x, y\right)$ and $\left(−3, 2\right)$
Step 1(b):
Use the distance formula.
$d=\sqrt{(x_{1}-x_{2})^{2}+(y_{1}-y_{2})^{2}}$
Answer (b):
$\sqrt{(x+3)^{2}+(y-2)^{2}}$
