Each of these coordinates are the coordinates of x and f of x. This is equal to 6 minus 0 is 6. These are all equivalent ways of viewing the same thing. That is going to be over negative 3 minus 3.

So the first thing we can do is figure out the slope. When we move in x, when our change in x is 1, so that is our change in x.

As you are reading and analyzing the word problem, if you find that you can set up an addition problem, and you have a set total constantthen you will be able to write an equation in standard form. So what are we going to get?

So, stick with me - it will all come together and make sense. So you could just write f of x is equal to 2x right here. We also have information for the price of the hot dogs and the price of the sodas.

So once again, this is equal the negative 2. So change in y over change in x, change in y is 4 when change in x is 1. You will be writing these equations and solving them when you get to the Systems of Equations Unit.

Now, we can use this coordinate information, the fact that it contains this point, we can use that information to solve for b. Then this tells us that the point when x is negative 1, f of x is equal to 2.

So you get b is equal to So this is pretty straightforward. This is equal to what? This is the coordinate 3, 5. So we do 6 minus 0. So they tell us that f of 1. For more information, click here.

This is just a fancy way of saying that both of these two points are on the line, nothing unusual. Slope is change in y over change it x. But this is really the equation. The whole reason I did that is so that cancels out with that.

If I used these guys first, I would have to use both the x and the y first. It looks like my delta y, my change in y, is equal to 4 when my delta x is equal to 1.

Now we can do exactly what we did in the last problem. So y is equal to 0 when you have negative 2 times 5, when x is equal to 5 plus b. This is actually, on some level, a little bit easier. So change in x is 1.

And it has a y-intercept of 6. Negative 1 minus 1. Actually if you wanted to write it in function notation, it would be that f of x is equal to negative 2x. Now we have this one. So we get zero is equal to, well if we divide negative 3 by 3, that becomes a 1.

If you divide 6 by 3, that becomes a 2.the slope and y-intercept for a line is to rewrite the equation in slope-intercept form. EXAMPLE 2 Finding slope and y-intercept Determine the slope and y. Write each equation in slope-intercept form.
