Found this on another site...I went straight to #4 and it worked great.
There are at least four ways to do this in PowerPoint.
1) Cut and Paste
Select the current long dash, copy it (CTL + C) and then paste it where
you want (CTL + V)
2) Auto Correct
Type 2 hyphens (-) then a space then any letter then a space then delete
back to the long dash. Auto correct will sense the double hyphen and
replace it with a long dash.
3) Insert Symbols
While in the text box, click on Insert => Symbol... => (font) Times New
Roman and look most of the way down the grid for the dash 3 before the TM
symbol
4) Keyboard character shortcut
Press and hold the Alt key, then on the number pad type 0150 and release
the Alt key

A dash is a punctuation mark that is used to indicate a pause or break in a sentence. There are two main types of dashes: the em dash (—) and the en dash (–). Em dashes are longer and are used to set off a phrase for emphasis or clarity, while en dashes are shorter and are typically used to show ranges or connections between numbers or words.
An em dash is the width of an m. Use an em dash sparingly in formal writing. In informal writing, em dashes may replace commas, semicolons, colons, and parentheses to indicate added emphasis, an interruption, or an abrupt change of thought.
Check your keyboard it's between the number zero and the plus symbol at the top right of the regular 105+ US keyboard. This is a hyphen and not a dash. If you use the hyphen key, you must use it twice to make a dash, but this still is not a dash as there is a space between the two hyphens. There are two types of dashes. The en dash and the em dash. The en dash is bigger than a hyphen, but smaller than a em dash. The em dash is what most would want to use. The way to type is as follows: en dash - hold down the "alt" key and type 0150. em dash - hold down the "alt" key and type 0151 - Note the dash used in each of the instructions. The first is an en dash, and the second is an em dash. The character beneath them is a hyphen.

First of all, lets talk about the difference between the em dash and the en dash. The em dash [--] is longer (about the width of capital M) than the en dash [-] (about the width of capital N). Both are longer than a hyphen. In a non-formatted or limited format medium, such as this web site, the em dash is represented by two hyphens [--]. The en dash is used to indicate range of values, such as between dates and times. Eg. 'This book is written for ages 3-5' The em dash is used to indicate an interruption Eg. "By trying we can easily learn to endure adversity--another man's, I mean." (Mark Twain). Or to show an abrupt change in thought Eg. I wish you would--oh, never mind.
Riddle: What is the world's longest punctuation mark? Answer: The one hundred meter dash.
The average font size of a heading is 44. It is set as default in the PowerPoint presentation.
To make an em dash, you just type in two hyphens with spaces before and after -- the word processor will change it into a "long dash."
