Slopes (G.3 a,b) HOMEWORK (day 14): Objective: SWBAT find the slopes and their relationship to other lines (3.6/3.8) **hw/hw log/compass/graph paper/workbook p.81, 87 Dry erase board, marker and eraser Computer Lab: VDOE SOL practice, resources-practice items, end of course practice tools Warm-Up: SOL 1st Nine Weeks Questions (31-43), graded! HOMEWORK (day 14):

Label your paper like this: Fold your paper like a hamburger once and hotdog once. Label your paper like this: 5

Example: Given P(-2, 2), Q(2, 1), R(1, -1), and S(5, -2), determine if is parallel, perpendicular or no relationship to

Example: Graph the line that passes through the point (3, 5) that is perpendicular to TK with T(0, 2) and K(5, 0).

Rate of Change Is a comparison of how much one quantity changes, on average, relative to the change in another quantity. 1000 2000 60 120 180 (60,1000) (180,0) (0,2000) Because the line goes down it is descending 8(1/3) ft/sec

Practice! Practice! Practice! Use the dry erase markers with students. Have students plot and label two points, find the slope, draw a line perpendicular and a line parallel to the given. Also have students identify at least one point on the parallel line and one point on the perpendicular line.
