The Slope-Intercept Form is the definition of what a line is. The equation for the slope-intercept form is y=mx+b. This may look confusing, but it’s very easy to understand. M stands for the slope, which you should know about if you read my article on slopes, check that out if you didn’t :D. B stands for when the line crosses the y axis. Look at this picture! Do you see how the point b is touching the y axis? That is the b in the equation y=mx+b. Now, let’s move on to an example. For this first question, scroll down!

What is the answer to this equation?

Let’s see. Since the equation for a slope is y=mx+b and m equal the slope, let’s find the slope of this first. I’m going to choose 1,2 and 5,4. Now that I have my points, let’s subtract. 4-2/5-1= 1/2. Now that we know 1/2 is the slope, let’s plug it in our equation. y=1/2x+b. There! Now we just have to get b, which is 1.5. Now, let’s plug it in again. y=1/2x+1.5. This is our answer!

It’s just a line, why does it have to be so exact. Guess, that is how math is supposed to be. Thanks for the explanation. I need to get some Jello now.
