Math 10 – Week 14

This week in Math 10…

This week we learned how to find the slopes of a line.

Remember *                                                           

rise is the vertical line from one point to another. When you find the rise, if you move up to will positive and if you move down from the point it will be negative.

run is the horizontal line from the point. When you find the fun, if you move right it will be a positive number and if you move left it will be negative.

Follow these steps.

If you are given the red line you want to find 2 nice points (normally these fall on crossed lines)







I know that could have been hard to see so I added grid lines. In BLUE you will see the run and the rise lines.






In GREEN are how many grid squares I cross to hit the the spot the run hits the rise. In ORANGE is the line where the rise will run into the run. Luckily these lines are 6 and 6 long.




Remember Rise over Run here is how to find your slope.









Math 10 – Week 13

This week in Math 10…

This week we started the second half of our semester with Relations and Functions. It was easy at first to grasp but as we got a little further it got a but more difficult.

I am going to explain and show how to find the input (x) on a graph if it gives us the output (y) in function notation.

You are going to start by looking at the graph, then look at the formula given to you, find out what you know, this will help you find what you need to find, start with your output (as that is the number you have), go across to the point across from your output number, in this case 4, once you have found the number go directly down to see what your input number is; 2, that is your input, plug it into your formula that was given, and there is your solved answer.

Here is the video part to the explanation above.
