7-14.

Find the distance between each pair of points.

$\left(3, 7\right)$ and $\left(8, 7\right)$
Hint (a):
Graph the points.

$\left(−13, 7\right)$ and $\left(8, 7\right)$
Hint (b):
Use the same method as in part (a).
Answer (b):
$21$ units away

$\left(x, 7\right)$ and $\left(c, 7\right)$
Hint (c):
How do you find the distance between two numbers?
Answer (c):
$| x − c |$ units away

$\left(5, 2\right)$ and $\left(5, 38\right)$
Hint (d):
Graph the points. How is this different from part (a)?

$\left(5, −4\right)$ and $\left(5, 34\right)$
Hint (e):
Use the same method as in part (d).

$\left(5, y\right)$ and $\left(5, f\right)$
Hint (f):
