Final answer:

To graph y = 15x - 600, create a table of x and y values, plot those points, and connect them with a straight line. The equation is in slope-intercept form, with a slope of 15 and a y-intercept of -600.

Step-by-step explanation:

How to Graph the Equation y = 15x - 600

To graph the equation y = 15x - 600, you would follow these steps:

  1. Plot points using a table of x and y values.
  2. Connect the points with a straight line.
  3. Use the slope-intercept form of the equation, which is already given in y = mx + b format, where m is the slope and b is the y-intercept.

To create a table of values, you can choose different x-values and calculate the corresponding y-values based on the equation. For example:

  • If x = 0, then y = 15(0) - 600 = -600.
  • If x = 40, then y = 15(40) - 600 = 0.
  • If x = 80, then y = 15(80) - 600 = 600.

Plot these points on the graph and draw a line through them, ensuring it extends in both directions beyond the plotted points. The slope of this line is 15, indicating the line rises 15 units for every 1 unit it moves to the right. The y-intercept is -600, indicating where the line crosses the y-axis.

The correct answer to the provided multiple choice question is d) All of the above.
