The equation y=0.5x+40 represents the monthly cost y in dollars of lesley's cell phone, where x is the of talk minutes over 750 that lesley uses.

graph the equation.

how did you determine the range of values to show on each axis of your graph?

You already have the equation given which is y=0.5x+40. To graph, you just have to replace random values of x to determine the corresponding values of y. Plot these points and connect them. The graph is shown in the attached picture. As you can observe, the range starts from y=40. This is because the y-intercept is 40. So, you don't have to show the y-values below because it would just minimize your linear graph.

The correct answer is 10%
