AL INTERPRETING POINTS As you work through this booklet, discuss your answers with your
neighbours and try to come to come agreement
1. The Bus Stop
Who is represented by each point on the scattergraph, beko?
The Bust Stop:
Interpret the points.
Each point represents
one of the people in
the line. You can see
how tall they each are
and you can make
assumptions on their
age.
You MUST use the
line strategy. You
will not receive
credit if you do not
draw in the
horizontal and/or
vertical lines as
proof.

Use the horizontal and
vertical line strategy
to figure out the order
of their heights and of
their ages. Write the
number of the point
by the person's name.
Don't forget the baby!

After a dreary day of rain, the sun peeks through the clouds and a rainbow forms. you notice the rainbow is the shape of a parabola. the equation for this parabola is y = -x2 + 36. graph of a parabola opening down at the vertex 0 comma 36 crossing the x–axis at negative 6 comma 0 and 6 comma 0. in the distance, an airplane is taking off. as it ascends during take-off, it makes a slanted line that cuts through the rainbow at two points. create a table of at least four values for the function that includes two points of intersection between the airplane and the rainbow. analyze the two functions. answer the following reflection questions in complete sentences. what is the domain and range of the rainbow? explain what the domain and range represent. do all of the values make sense in this situation? why or why not? what are the x- and y-intercepts of the rainbow? explain what each intercept represents. is the linear function you created with your table positive or negative? explain. what are the solutions or solution to the system of equations created? explain what it or they represent. create your own piecewise function with at least two functions. explain, using complete sentences, the steps for graphing the function. graph the function by hand or using a graphing software of your choice (remember to submit the graph).

What is the slope of the line that passes through the points (–9, 2) and (0, 4)? the slope of the line is

Use the linear combination method to solve the system of equations. explain each step of your solution. if steps are not explained, you will not receive credit for that step. 2 + 9 = −26 −3 − 7 = 13
