10-151.

Find the distance between the two points.

1. $\left(x, y\right)$ and $\left(−3, y\right)$

Notice that the y values are the same. (the line is horizontal)

Just subtract −3 from x to find the distance.

x + 3

1. $\left(x, y\right)$ and $\left(−3, 2\right)$

Use the distance formula.

$d=\sqrt{(x_{1}-x_{2})^{2}+(y_{1}-y_{2})^{2}}$

$\sqrt{(x+3)^{2}+(y-2)^{2}}$
