MPM1D Determining Linear Equations 2017-11-16

Determining the slope-y-intercept form

Homework

Find the linear equation in the form $y=mx+b$ for each situation.

Given the following point on the line and the slope:

$(2,2)$ and $m=5$
$(-5,3)$ and $m=\frac{1}{2}$
$(\frac{1}{2},4)$ and $m=-\frac{1}{3}$
$(0,-10)$ and $m=\frac{11}{17}$

Given the following two points on the line:

$(2,4)$ and $(-3,5)$
$(7,-1)$ and $(-7,12)$
$(\frac{1}{2},2)$ and $(-3,\frac{5}{2})$
$(2,11)$ and $(18,11)$

Sampling

I’ll post the Bias stuff tomorrow.

MDM4U Dice Simulation Practice 2017-11-07

We worked together to simulate another dice game today:

Dice Simulation – Primes Pairs Squares

You have an in-class assignment tomorrow. You can use any of your past work to complete it, and it’s due by the end of the day this Friday.

MPM1D Running Data 2017-11-07

We worked on the scatter plots from yesterday then spent the last half hour or so looking at this problem:

Running Data Sample – Scatter Plot

It’s homework!

Retests for all classes

Midterm report cards are coming out soon and lots of people want to demonstrate their learning beforehand. If you would like to rewrite a test from earlier in the semester you can do that:

at lunch on Thursday (9th) or Friday (10th)
during Period 3 or 4 on Thursday or Friday (if you have a spare only)
after school on Thursday

You have to let me know in advance that you’re writing.

For Grade 9s:

Test 1 – Evaluating and Simplifying Expressions

Test 2 – Solving Equations

For Grade 12s:

Test 1 – Combinatorics

Test 2 – Introduction to Probability

MPM1D The Language of Scatter Plots 2017-11-06

We worked on the kinds of trends we can see when collecting data and using scatter plots to show it. Here are the words we used:

Linear vs. Non-Linear
Increasing or Positive Correlation
Decreasing or Negative Correlation
No Correlation vs. Weak, Moderate, Strong, and Perfect

We sketched some sample graphs for each to show the differences. We then discussed how to sketch a line or curve of best fit on those scatter plots.

We spent the last 25 minutes or so carefully graphing a data set and correctly labeling everything. You have three more to finish for homework, including the lines or curves of best fit. Here’s that page:
