Question

The depreciated value y (in dollars) of a business car after x years

y = -4200x + 21,000.

a. Graph the equation.

Answer 1

To graph the equation y = -4200x + 21,000, plot points on a coordinate plane by substituting different values of x into the equation to find corresponding y-values, and then connect the points with a line.

Step-by-step explanation:

To graph the equation y = -4200x + 21,000, you can plot points on a coordinate plane. Choose different values for x, substitute them into the equation to find the corresponding y-values, and plot the points.

To graph the equation y = -4200x + 21,000, plot points on a coordinate plane by substituting different values of x into the equation to find corresponding y-values, and then connect the points with a line.

Then connect the points with a straight line. For example, when x = 0, y = -4200(0) + 21,000 = 21,000. When x = 1, y = -4200(1) + 21,000 = 16,800. Plot the points (0, 21,000) and (1, 16,800) on the coordinate plane and draw a line through them.
