11/16/11 Honors Algebra

Lots of students were attending e-Conference today with DECA.

After discussing questions from practice sheets 81 & 82 – Writing equations of lines given one-point & slope / given 2-points;  Specifically page 82  #8 and 11…

#8   (4, 8) (4, -2) When we graph these points – we have a vertical line; when we calculate slope, we have undefined slope – so how do we write an equation to represent this line?  What do you notice about the points?  The x’s are both 4.  Eq: x = 4

#11 (0, 2) (-4, 2)  When we graph these points – we have a horizontal line, when we calculate the slope, we have zero slope – so how do we write an equation to represent this line?  y = 0x + 2…OR we could simply look at the points, notice the y’s are both 2.  Eq.  y = 2

During class, we looked at writing equations for parallel & perpendicular lines.  See links for examples.

More work with LINES

Continue to practice translating between standard form and slope-intercept form.  Target/Practice Quiz today; 

HW ?:

Toy Trucks

Truck A travels at a rate of 15 inches per second;  At 5 seconds, it is at 91 inches.
Truck B travels at a rate of 7 inches per second;  At 5 seconds, it is at 20 inches.
If the starting line is at 0 inches, determine where each truck started (ie in front of or behind the starting line and at what measurement).  Be able to explain your reasoning.

Looking ahead to Friday – writing equations of lines given slope & a point (refer back to geogebra activity).


Geogebra & Y=mx+b

Use problems from pages 81 & 82 for problem sets.

Go to Geogebra

Create a line by plottting information given (either point and another point using slope, or two points).

From the graph, determine the slope and y-intercept of your line and write an equation to model the line.

Wednesday, we will algebraically write the equation to verify if your equations are correct.  This will hopefully help you make connections between both the visual (graph) and algebraic (equation) models.
