5 things Math 10

If I could go back and change anything about my math 10 experience I would tell myself these things:

  1. Do your homework, because it helps you remember everything so much easier.
  2. Go to tutorials if you don’t get anything even if its just the simplest thing its worth it to figure it out rather then not asking.
  3. Start studying for the midterm farther ahead, I left this until last minute and it showed in my test score and if I could back I would change it.
  4. Do your blogposts every week, because otherwise you are going to have like 4 to do at once and its much harder to do then just sticking to 1 every week.
  5. When studying practice it by writing and trying equations, it helps you to remember it better.

 

Week 15- Slope of a line segment

Using the equation y=mx+b we can solve for a (straight) line. When using this equation you plug things in and then you add your co-ordinates to make your equation fully solved. When using this equation it can be tricky to know which variables stand for what (plug-ins) but after practicing it will just come naturally. M stands for the slope so the rise/run between to points on a graph (that are on your line) and b stands for your y intercept, but don’t be fooled it can be negative OR positive depending on the line you are dealing with. Once you have those two you solve for the other then you plug in two of your co-ordinates to evaluate for the rest of the line.

For example a line that passes through the point (0,2) <on the y axis x=0 so it is an intercept> with a slope of \frac{5}{2}

In the photo below I have shown you how this would look on a graph and how you would be able to find it using the information given.
