Slope pages 139-140 Slope-Intercept page 147-148 (graphing T12 page 148 of Khan Practice) Point Slope pages 151-152 Standard Form 155-156 Parallel & Perpendicular (T17) pages 159-160 Combined functions / values T8-T9 Khan Academy – Functions 3 How to find Inverses Cool Math Inverses ONline examples at CoolMath for Lines you can use their examples and/or Lines Practice (scroll to bottom of the link) to find practice problems.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.

Also – HW! Retake your Linear Pre-Test!

More work with LINES…

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

HW ?:

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

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.
