This week, we learnt how to find the slope of a line. The slope of a line is . The numbers that we’re using are (3,12) and (2,4). The 3 and the 2 are the x coordinates and the 12 and 4 are y coordinates. To find the rise, you have to subtract the two y coordinates. 12-4=8 so, the rise is 8. To find the run, you subtract the…

This week we learnt how to find the length of line segments. A line segment can be found on a graph and is often labeled on either end with letters (like A,B). To find a line length the question will give you the coordinates for where the line starts and finishes. For example they might tell you: point A(3,3) and point B(5,7) and ask you to find the distance from…

This week we learnt how to write function notation as well as find an answer to a equation written in function notation. You might start with an equation that looks like this: f(x)=3x+6 The question will most likely tell you that x equals a certain number. So, we’ll say that x=4 Next, you replace the 4 with any spots that say x so the equation is now f(4)=3(4)+6 Now, you…

This week we learnt how to figure out the x and y placements on a graph by solving an equation. You might receive an equation that looks like this: x=y+4 If you’re trying to solve for x, then the y always equals 0. If you’re trying to solve for y then the x is always equal to 0. So, your first step is to re-write the equation by replacing the…
