How to Find the Scope of an Equation

How to find the scope of an equation. I'm Bon Crowder and we're talking about equations today and specifically how to find the slope of an equation. So here we have an equation and we need to know that a linear equation, first of all linear equation is the only type of equation that has a slope, so this is a number as well, so a linear equation can always be written in this form where this is the slope and this guy hanging off here is the Y intercept. Okay, so this one is in the right format, the right template. So this is 3X + 2 so this is the slope and this is that Y intercept. So that's one way to find the slope of an equation. It has to be a linear equation and there's your slope. What if we've got a guy like this? It's still a linear equation but he's not in the right shape. So what do we do? We make him into the right shape. So we need to solve for Y so I can subtract 3X from both sides, so I have 4Y is -3X + 7 and divide by 4. So Y =, now the 4 distributes because I have this +, -3/4X + 7/4. Now this is not near as pretty as Y = 3X + 2 but it's still in the same shape. You have a number right here and a number right here and guess where the slope is, right there. So, that's how you find the slope of an equation. I'm Bon Crowder, have fun with it.
