• # Quiz - Review (Part 2)

Posted by Kurt Waldner on 1/24/2020

Today in class, we took a second quiz, just on the review topics.

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

• # Returned Quiz

Posted by Kurt Waldner on 1/23/2020

Today in class, we returned and checked the quiz on point slope.  This was a weird quiz...the first part (the new stuff) was pretty good.  The second part (the review) was pretty bad!  Tomorrow, we will do a second quiz on the review.  The results will be averaged with the first quiz.

For homework, review!!

• # Quiz - Point Slope and Review

Posted by Kurt Waldner on 1/22/2020

Today in class, we took the quiz on point slope, slope intercept, and some review.

There is no homework.

• # Point Slope and Slope Intercept

Posted by Kurt Waldner on 1/21/2020

Today in class, we checked (and completed and checked) the homework on point slope and slope intercept.  Obviously for both equations, we need to know the slope.  This is vital.  When using point slope, it doesn't make a difference which point you use to convert to slope intercept form.  As always, students need to be careful with the negatives and the basic math.

For homework, review for the quiz.

• # Point Slope and Perpendicular

Posted by Kurt Waldner on 1/17/2020

Today in class, we continued working with point slope.  We switched from parallel lines to perpendicular lines.  Therefore, we needed to find the opposite reciprocal of the original slope.  We completed the remaining problems and then worked on the assignment.

For homework, complete Homework #6.  Have a wonderful long weekend.  GO LIONS!!

• # Point Slope and More Parallel

Posted by Kurt Waldner on 1/16/2020

Today in class, we finished the practice problems which gave us two points and asked for both equations (point slope and slope intercept). Once we finished working through the problems, we brought back an old concept...parallel lines.  Once again, we needed to find the original slope then use the parallel slope (which is the same) and write the point slope equation and then the slope intercept equation.  These problems are truly a combination of a few concepts.  Tomorrow, we will go through the perpendicular problems.

There is no homework.

• # Point Slope Formula

Posted by Kurt Waldner on 1/15/2020

Today in class, we discussed the third method of writing a linear equation:  Point Slope.  So far, we have looked at Standard Form (Ax+By=C) and Slope Intercept (y=mx+b).  Point Slope is y-y1=m(x-x1).  We worked on a few examples, graphed the data, and converted the equation into slope intercept form.  We will finish up this portion tomorrow and then work on more parallel and perpendicular problems.

For homework, complete the remaining problems on point slope.  Remember to first find the slope, use the first point in the point slope formula, use the second point in the point slope formula, then finish by writing the equation in slope intercept.

• # Finished Quiz, Returned Quiz

Posted by Kurt Waldner on 1/14/2020

Today in class, we finished the 36 point quiz on slope, slope intercept, parallel, and perpendicular.  After a few minutes to grade the quizzes, we returned and checked the quiz.  Students should be prepared on future quizzes to have review material.

There is no homework.

• # Quiz - Slope, Standard Form, Parallel and Perpendicular

Posted by Kurt Waldner on 1/13/2020

Today in class, we took the quiz on using slope, slope intercept, and standard form.  There was also some review tied into the quiz.

There is no homework.

• # Parallel and Perpendicular (Based on Slope)

Posted by Kurt Waldner on 1/10/2020

Today in class, we finished going over the homework using slope intercept to determine if lines are parallel, perpendicular, or neither.  Once we checked the solutions, we reviewed for the upcoming quiz.

For homework, review for the quiz on Monday on slope intercept, standard form, parallel, and perpendicular.  Have a warm weekend.  GO LIONS!!
