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
3 practice problems:
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;
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.
Student choice of online resource – depending on area of need; linear functions – current unit; polynomials; systems of equations; Met with individual students to clear misconceptions/mistakes on solving equations; some students submitted for retake on assessment.
