Algebra 2H pds 1,4
We began the unit on 2 variables with the graphing of a line and its forms. There's standard form, slope-intercept form, and point-slope form.
HW page 129 # 7,11,15,17, and page 141 # 7,11,15,19,31, and 35.

EC problem- Graph the equation 3x -4y = 12 using the x and y intercept method. Then, show that the line will be the same if you solve for y and use the slope-intercept form.(In other words, graph this equation twice using two different methods.)

Geometry H pds 2,5
Today was the Test on Chapter One. It covered many different topics.
A puzzle on Complementary and Supplementary Angles was given out afterwards. It will be collected on MOnday so make sure you do the work!

EC problem- Two angles are supplementary. One angle is 3x and the other angle is 2x-10. Find the measure of each angle.

Trig pd 6
We began the second chapter today. We went over how to calculate the exact values of the trig functions of 0º, 30º, 45º, 60º, and 90º angles. We also learned about cofunctions.
