This week in math 10 I learned how to graph relations on desmos and how to find each dot. I had to graph these on little charts in my workbook. Then I had to find each coordinate and label where it was on the line.

To do this on desmos I had to type in the relation

one example would be

Then I had to see how the line was on desmos. I needed to check where it went on the x axis, y axis, or sometimes both. Then I found the coordinates that had a dot on the line. For this example, the coordinates (the dots on the line) were…

(-1, 0), (0, -6), and (6, 0)

There are obviously more coordinates, but these were the most noticeable ones that didn’t include a decimal.

Another thing I learned (remembered) this week that relate to this were how to create a coordinate and how to sketch it. First, I learned that the first number to show should be the number that goes along the x-axis. The x axis is the horizontal line on the graph. Then I learned that the second number is the one that goes along the 7-axis. This is the vertical line on the graph.

Most things I have learned this week are just little reminders from last year. I learned a lot about graphing and the s and y intercept and axis. So, most of these things I already learned just not in this much detail and difficulty.

This week during math 10 we have been reviewing linear relations that we learned about last year in math 9. I learned how to label a pattern.

example of an example would be:

2, 4, 6, 8… then you will have to figure out how much it goes up by and what number the pattern starts with.

So, for this one it would go up by 2 and starts at 2

So, the relation would be that it goes up by 2 and across by 2 if I would put it on a graph.

Another thing I learned is how to use a table of relations

example would be:

The left side of this table is going up by 1 and the right side is going down 2 twice then up 4 then down 2 twice and continuing…

In order to graph this you must write it in brackets

Example. (x,x)

In order to make this work you need to put the information from the x table first then the y table

So it would work like (0,4)

We are still learning about this chapter and this is what i’ve taken in so far.
