Graph the function (equation):


To graph, you will need to make two points. The graph will automatically create your line for you.

  • Click a Graph tab (Graph 1, Graph 2, and so on) for each graph you need to plot.
  • Click on the graph background to add a point. Add two points to create a graph. Drag a point or type in x and y coordinates to edit its position. Click on a point to delete it.
  • After creating your graph, you can check the dashed line box.
Which of the following situations best represents a proportional relationship?
A clothing store sells 10 skirts online each day plus 8 skirts per hour in the store.
A bakery makes 6 loaves of bread every 1/2 hour or 12 loaves every hour.
A tree expert earns $45 per hour plus $25 for service calls.
A cell phone company charges $50 per month plus $10 per phone number.
The graph shows the relationship between the number of gallons of fuel remaining in the tank of a semi truck and the number of miles traveled by the semi truck.



Which function can be used to find y, the number of gallons of fuel remaining in the tank of the semi truck after it has traveled x miles?
The graph shows a relationship between x and y.

The graph shows a proportional relationship because the x and y intercepts both contain 7.
The graph shows a proportional relationship because the graph passes through 3 different quadrants.
The graph shows a non-proportional relationship because the graph has a negative slope.
The graph shows a non-proportional relationship because the graph does not contain the origin.
