Calculating Slope - Directions
Using the Calculating Slope Concept Builder is quite simple. There are three difficulty levels. Each level involves he same task and the same directions - calculate the slope of a line, enter it into the answer field and tap on the Check Answer button. To determine the slope, you will need to know the coordinates of points on the line. There are six data points on every graph. Tap on a data point to view the x,y coordinates for that data point. They are displayed above the graph. Once you calculate the slope from the coordinate values, you will have to enter it into the answer field. You can do this one of two ways. You can tap into the answer field and enter the value using the keyboard of your device. This works great if you're working on a computer. But if you are on a mobile device, we recommend that you use our built-in number pad. Simply tap on the number pad icon. When you do, a number pad will pop up along the right side of the Concept Builder. Use the number buttons of the Number Pad to enter your answer. Then tap on the Enter button at the bottom of the Number Pad. When you are satisfied with your answer, tap on the Check Answer button. You will receive immediate feedback and your Progress Report will be updated.
Your goal is to earn "Stars" and to complete one or more difficulty levels. Stars are earned when you show success on a particular question. Once you show success on all the questions of a particular level, you will earn the Trophy for that level.
