Sally has only nickels and dimes in her money box. She knows that she has less than $20 in the box. Let x represent the number of nickels in the box and y represent the number of dimes in the box. Which of the following statements best describes the steps to graph the solution to the inequality in x and y? A) Draw a dashed line to represent the graph of 5x + 10y = 2000, and shade the portion above the line for positive values of x and y. B) Draw a dashed line to represent the graph of 10x + 5y = 2000, and shade the portion above the line for positive values of x and y. C) Draw a dashed line to represent the graph of 5x + 10y = 2000, and shade the portion below the line for positive values of x and y. D) Draw a dashed line to represent the graph of 10x − 5y = 2000, and shade the portion below the line for positive values of x and y.

1. Write an equation in slope-intercept form of the line that passes through the given point and is parallel to the graph of the given equation. (1,-3; y + 2 – 4(x-1)2. Are the graphs of the equations y = -2x +3 and 2x +y = 7, parallel, perpendicular, or neither? Explain.3. A line passes through (5,0) and is perpendicular to the graph of y +1 = 2(x-3). What equation represents the line in slope-intercept form?4. A bike path is being planned for the park. The bike path will be parallel to Main Street and will pass through the park entrance. What is an equation of the line that represents the bike path? (use image from Ex.4)5. Determine whether this statement is always, sometimes, or never true. Two line with the same slope and different y-intercepts are perpendicular.
