Slope Intercept Form
I'm sure you've heard of slope intercept form before, but do you actually know what it means? GradeA will give you a trick to help you remember this easy formula because we will teach you to truly understand it.
The first thing you need to understand is that it is simply an equation that represents a straight line. Because lines can go in any direction, the numbers in the equation are used to tell you what direction the line should go.
There are two important numbers in this form of a line: one number represents the slope, and the other number represents the y-intercept. Now do you see why it was given this name - makes sense, right? Okay, next let's take a look at some GradeA tricks and finally we'll see some examples...
Use these tricks to help you:
- y-intercept = b which stands for the beginning
- slope = m which stands for the move
The little tricks will be especially helpful when you have to graph a line with the slope intercept form. You will plot the "beginning" point first on the graph, and then you will move the right number of places to make the "move." Simply connect the dots and you have graphed your line!
