11/16 Warm Up- Monday 11/16 Objective I will be able to determine whether lines are parallel, perpendicular, or neither and write equations of parallel and perpendicular lines. 11/16 Concept Builder 11/16 Concept Builder 11/16 Concept Builder 11/16 Concept Builder 11/16 Concept Builder 11/16 Concept Builder 11/17: Warm Up Tuesday 11/17 Objective I will be able to determine whether lines are parallel, perpendicular, or neither. 11/17 Assignment Parallel and Perpendicular Lines Worksheet 11/18: Warm Up Wednesday 11/18 Objective I will be able to graph parent function of linear equation. 11/18 Activity Meet the Parent Activity. Guess the age of the following celebrities. 11/19: Warm Up Thursday Parallel lines have the 1)__________ slope. Same in math means 2)__________. Perpendicular lines have 3)__________ 4)__________ slopes. Negative reciprocal means 5)__________ signs and 6)__________ fractions. Word Bank: opposite flipped same reciprocal negative equal 11/19 Objective I will be able to predict transformation of linear parent function using slope and y-intercept. 11/19 Concept Builder Parent function: the most basic form of an equation: linear y = x 11/19 Concept Builder Parent function: basic form of equation: linear y = x Reflection: reflected across x-axis 11/19 Concept Builder Parent function: basic form of equation: linear y = x Translation: slides up or down the y-axis 11/19 Concept Builder Parent function: basic form of equation: linear y = x Stretch: stretches line toward y-axis; makes line more steep Compression (shrink): presses toward the x-axis; flattens the line Linear Transformations y= • y-coordinate: the y-value m (x) + b Linear Transformations y= m • slope: rise over run • - value: negative correlation; reflection over x-axis • more than 1: steeper; stretch • less than 1: flatter; compression (x) + b Linear Transformations y= m (x) + b • x –coordinate: the x-value Linear Transformations y= m (x) + b • y-intercept: where line crosses the yaxis • changes move line up or down • + value: moves up • - value: moves down Linear Transformations y= • y-coordinate: the y-value m • slope: rise over run • - value: negative correlation; reflection over x-axis • more than 1: steeper; stretch • less than 1: flatter; compression (x) + b • x –coordinate: the x-value • y-intercept: where line crosses the yaxis • changes move line up or down • + value: moves up • - value: moves down 11/20: Warm Up Friday y = m (x) + b • Word bank: • negative value: compresses moves down moves up reflects stretches • bigger than one: • smaller than one: • positive value: • negative value: 11/20 Objective I will be able to predict transformation of linear parent function using slope and y-intercept.
