line intercept plus slope, and that's simple regression.

We could even write it in slope intercept form.

Welcome to the presentation on slope and y intercept.

You have an a intercept or y intercept of 50, and the slope is negative 1.

The y intercept is 10 and the slope is 1.

What is the equation of this line in slope intercept form?

Where m is the slope and b is the y intercept.

Here's our regression equation. We have the intercept and the slope.

No, it still seems like my slope see the y intercept,

We are now gonna do some slope and y intercept problems as well. y intercept problems as well.

And this is already in mx plus b form, or slope intercept form.

Now, as I change the slope and the y intercept for this graph,

This presentation isn't going to teach you how to solve for slope and y intercept, but hopefully it will give you a good intuition of what slope and y intercept is.

So any line can be represented in slope intercept form as y mx b.

So we see the y intercept is 2, and its slope is negative 1.

This is the y intercept and we see that the slope is negative one two.

So B sub zero again is just the intercept for the slope of the line.

The y intercept here is y is equal to 3, and the slope here is 1.

Yeah, I think that looks like the right slope, but the y intercept has to be lower.

Intercept

Slope of negative 1, that's what's multiplying the independent variable, and then you have a y intercept of 50, or maybe we should say an a intercept.

So we have a y intercept of negative 2, 1, 2, and now the slope is 1 2.

The intercept.

Red's y intercept?

So if we were to just map this into the traditional slope intercept form, we don't have x's and y's here.

The y intercept is one, which is exactly here, zero comma one, and the slope is one, and that's pretty obvious.

So, the predicted score on y was the regression constant, or the intercept, and the slope times an individual's score on x.

So, 33.16 is just the intercept in this analysis and'negative point 13' is the slope of the line relating age to endurance.

That's one potential intercept.

The y intercept just tells us where we intercept the y axis.

If we put it in slope y intercept form, the equation of really, any line is y is equal to mx plus b.

Slope Practise

So if I were to write this in traditional slope intercept form, I could rewrite this as x is equal to 2 minus y.

So the intercept is 33.16.

So that's the x intercept.

So y intercept oh boy, how did that happen, that was strange y intercept
