This week we learned about equations, and how all of the numbers and variables mean something. The number beside the x in an equation is equal to the slope and the last number is the y intercept. In a example below I am going to show and explain how a t-chart, graph and equation can all represent the same thing. If you have one of these things (a graph or t-chart or equation), you can make the other 2 with just that information. I found it cool how all of these are intertwined and how they are related. Even though they all look very different they contain and display the same information, it doesnt matter how you present it, in either of the 3 ways the viewer will take out the same data.
Things to know:
- the number beside the x is the slope
- the last number that you add or subtract is the y-intercept
- the slope is equal to rise/run
- if the slope is a whole number you put that number over 1 (run=1)
- in a t-chart when displaying the data the rise=y and run=x (add the run of the slopes fraction to the first column which is x, and the top number of the slopes fraction to the second y column of the t-chart)
