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?
draw a dashed line to represent the graph of 5x + 10y = 1500 and shade the portion below the line for positive values of x and y.
draw a dashed line to represent the graph of 5x + 10y = 1500 and shade the portion above the line for positive values of x and y.
draw a dashed line to represent the graph of 10x + 5y = 1500 and shade the portion above the line for positive values of x and y.
draw a dashed line to represent the graph of 10x – 5y = 1500 and shade the portion below the line for positive values of x and y.
