That's 0 coma 13 over 3 or 0 coma 4 and 1 thirds. And all it does is tell us the change in y you go from this point to that point We have to go down, our rise is negative we have to go down Let's quickly review the steps for writing an equation given two points: 1. Based on your equation, how many participants are predicted for the fifth year?
Write an equation that can be used to predict the amount of participants, y, for any given year, x.
Remember a point is two numbers that are related in some way. All we need to do is substitute!
You can look at that visually there or you can use this formula same exact idea, our ending x-value, our ending x-value is 5 and our starting x-value is negative 1.
Now you will have to read through the problem and determine which information gives you two points. So this y-intercept right over here.
So negative 1 coma, 1, 2, 3, 4 ,5 6. And to do that, we can use the information that we know in fact we have several points of information We can use the fact that the line goes through the point -1,6 you could use the other point as well. That is equal to negative And we can write these as mixed numbers.
