• # Graphing Equations

Posted by Kurt Waldner on 1/24/2020

Today in class, we used the entire class to check Page 214 #40-48.  We reviewed how to create a table of coordinates to graph.  We also reviewed how to solve an equation for y.  This is extremely helpful if we want to use some cool mathematical short cuts for graphing.  We'll investigate more into these equations next week.

There is no homework.  Have a wonderful weekend.  GO LIONS!!

• # Plug It In and See If It Works!

Posted by Kurt Waldner on 1/23/2020

Today in class, we rather quickly checked Page 213 #3-6 and 16-21.  We then used the remainder of class to work on Page 214 #40-48.  These were all graphs.

For homework, complete Page 214 #40-48.

• # NO CLASS (Absences)

Posted by Kurt Waldner on 1/22/2020

Due to less than 50% of the class being present, we did not have class.

For homework, complete Page 213 #3-6 and 16-21.

• # Solving for WHY???

Posted by Kurt Waldner on 1/21/2020

Today in class, we checked the solutions (after giving some additional time to complete the homework from FRIDAY!) on Page 213 #7-9 and 22-30.  These problems required students to solve equations for y.  Once again, this is just undoing everything or using the opposite operation to solve.  We then used the remainder of class to work on Page 213 #3-6 and 16-21 which asked students to determine whether a point is a solution or not...plug it in.  If it works, it is a solution.  If not, it is not a solution.

For homework, complete Page 213 #3-6 and 16-21.

• # Equations, Tables, and Graphs

Posted by Kurt Waldner on 1/17/2020

Today in class, we finished looking at the various equations, tables, and graphs.  We made some very valuable and mathematically important observations.  We then started to work on Page 213 #7-9 and 22-30.  In each of these problems, we need to solve for y.

For homework, complete Page 213 #7-9 and 22-30.  Have a wonderful weekend.  GO LIONS!!

• # Do You See What I See??

Posted by Kurt Waldner on 1/16/2020

Today in class, we took the majority of the class to look and think.  We looked at the eight equations, tables, and graphs we completed the past few days and thought about all the similarities and the patterns among the equations, graphs, and tables.  I was impressed by some of the observations.  All of our observations were based on equations solved for y.  Here were a few of our discoveries:

• If the number multiplied with the x is positive, the graph will be increasing.  If the number is negative, it will be decreasing.
• If the number multiplied with the x is positive, the table will add the same number to find the y-value in successive x-values.  If the number is negative, it will subtract.
• The number added or subtracted from the x term is the value of y when x=0.  This is a great place to start in the table.

There are more things to see and hopefully we will be able to notice them tomorrow.

For homework, look at the eight graphs and see if there is a relationship between the number added or subtracted from the x term and the graph.

• # Even More Graphing!

Posted by Kurt Waldner on 1/15/2020

Today in class, we continued to graph various equations.  We focused on equations with fractions and how to select x-values that would make finding the corresponding y-value "easy" (typically a multiple of the denominator of the fraction).  Tomorrow, we will really try to analyze the equations, graphs, and tables.

There is no homework.

• # More Graphing

Posted by Kurt Waldner on 1/14/2020

Today in class, we continued working on graphing an equation of a line.  Students should be looking for patterns in these problems which will help us tremendously in the future

There is no homework.

• # Quiz and Graphing

Posted by Kurt Waldner on 1/13/2020

Today in class, we took a quick quiz on plotting points and quadrants.  After the quiz, we worked on graphing an equation of a line.  We did this by substituting in specific x-values, calculating the corresponding y-value, and then plotting the resulting coordinate.  Students should be looking for patterns in these problems.

There is no homework.

• # Plotting Points

Posted by Kurt Waldner on 1/9/2020

Today in class, we collected the graphing assignment (1/3  finished, 1/3 did a portion, 1/3 lost it!).  We then used the entire period to work on the assignment.

For homework, complete Page 206 #1-26 and 208 #36-39.
