At a discount entertainment website, she sees that each CD costs $7 (tax included) and each DVD costs $10 (tax included). If she will buy three times as many CDs as DVDs, how many DVDs will Ariana buy without exceeding $300? 8 5. Write an equation of a line in standard form that has a slope of β 7 and a y-intercept of 2. 6. Line m passes through the points (4, -2) and (7, 8). What is the slope of the line that isβ¦ a. Parallel to line m b. Perpendicular to line m 7. Write a linear equation for each of the following pairs of points by first finding the slope: a. (2, 12) and (2, -4) b. (7, -5) and (4, -5) c. (1, 12) and (0, 9) 8. Simplify the following: β300 + 4β27 Name ______________________________________ Date ______________________ Block ________ 9.
