Find the distance between (-7,2) and (9,2) express answer in simplest radical form

Use the Pythagorean Theorem OR the distance formula (they are based upon the same principles).

The x-component of this distance is the distance from -7 to +9, which is 16.  If you're unsure of why, graph a number line, plot -7 and +9 and then count the number of scale divisions between the two.

The y-comp is the distance from 2 to 2, which is zero.

Thus, the distance between the two points is sqrt(16^2+0^2), or 16.

Step-by-step explanation:

4.12

Step-by-step explanation:

distance = [tex]\sqrt{(-7-1)^{2} +(3-4)^{2} } = [tex]\sqrt{-8^{2} +-1^{2} }[/tex]

= [tex]\sqrt{16+1}[/tex]

= [tex]\sqrt{17}[/tex]

=4.12
