 Score Description Sample Activity 4.0 (advanced) In addition to Score 3.0, the student demonstrates in-depth inferences and applications regarding more complex material that go beyond end of instruction expectations. Suppose a 5-minute overseas call costs $5.91 and a 10-minute call costs$10.86.  The cost of the call and the length of the call are related.  The cost of each minute is constant.         A.  What is the cost, c, of a call of m minutes duration?        B.  How long can you talk on the phone if you have \$12 to spend? 3.5 In addition to Score 3.0 performance, the student demonstrates in-depth inferences and applications regarding the more complex content with partial success. 3.0 (proficient) The student can: Write linear functions given... point/slope 2 points parallel/perpendicular lines and a slope Write an equation in point-slope form for the line that has the given slope and that passes through the given point. m = 3  (0, -2) m = -2  (5,1) Write an equation in slope-intercept form that passes through the given points. (2,3) & (1,5) (5, -2) & (-16, 4) Write an equation in slope-intercept form for the line that passes through the given point and is PARALLEL to the given line. (4,5)  y = -2x + 4 (-7,3)  x = 4 Write an equation in slope-intercept form for the line that passes through the given point and is PERPENDICULAR to the given line. (5, -1)  y = 4x - 7 (4, -2)  y = 3 Write the equation of the function represented by the graph in slope-intercept form. 2.5 The student demonstrates no major errors or omissions regarding the simpler details and processes (Score 2.0 content) and partial knowledge of the more complex ideas and processes (Score 3.0 content). 2.0 (progressing) The student demonstrates no major errors or omissions regarding the simpler details and processes but exhibits major errors or omissions regarding the more complex ideas and processes (Score 3.0 content).   Can find slope between 2 points Write the equation of a line given the slope and y-intercept Find parallel/perpendicular slopes from an equation   However, the student exhibits major errors or omissions regarding the more complex ideas and processes. Write the equation of the line given a slope of 4 and a y-intercept of -5. Find the slope of the line that goes through  (-2, 5) and (3, 8). What is the slope of the line parallel to y=3x + 8 What is the slope of the line perpendicular to y=-4x - 6 1.5 The student demonstrates partial knowledge of the simpler details and processes (Score 2.0 content) but exhibits major errors or omissions regarding the more complex ideas and procedures (Score 3.0 content). 1.0 (beginning) With help, the student demonstrates a partial understanding of some of the simpler details and processes (Score 2.0 content) and some of the more complex ideas and processes (Score 3.0 content). - 0.5 With help, the student demonstrates a partial understanding of some of the simpler details and processes (Score 2.0 content) but not the more complex ideas and processes (Score 3.0 content). 0.0 Even with help, the student demonstrates no understanding or skill. -
