A&W MATH 11: SLOPE
A) Lets define:
Ratio:
Example: On a hockey team, there are 12 forwards and 6 defencemen. As a
ratio, we write it as _ or _.
Proportion:
Example: if there are 12 forwards and 6 defencemen, how many forwards do
we have if there are 48 de

GRAPHING: TRENDS, ESTIMATING AND MISLEADING VALUES
1) A line graph can be used to show a trend. We can also use it to interpolate or
extrapolate some information.
Interpolate:
Extrapolate:
Ex:
growth of a bean plant:
i)
how tall is the bean plant a

GRAPHING
In this unit, we will look at different types of graphs and how they are used. We use
graphs to show information as a picture to make the data easier to understand and
use.
We will look at 4 main types of graphs:
i)
line graphs
ii)
A&W 11: CHP 1.2: PYTHAGORUS AND THE TANGENT RATIO
A) What is the Pythagorean Theorem?
If the triangle had a right angle (90) .
. and you made a square on each of the three sides, then .
. the biggest square had the exact same area as the other two squares

CHP 1.3: RATES OF CHANGE
A) -before, we found that slope is m =
-now: how to do it with points on a graph?
-equation: m =
Example: find the slope from this graph:
