Instructions

Click the graph tab.
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.

4

Match the slope to the graph.

Draggable item		Corresponding Item
negative slope
slope is undefined
slope is zero
positive slope

The Ramy Family wanted to buy salads and sandwiches but only wanted to spend $24. The salads cost $3 each and the sandwiches cost $4 each. The equation to model the situation of how many sandwiches and salads they can buy is represented by 3x+4y=24.

Grading for this problem:
2 points: correct graph
1 point: correct x-intercept
1 point: correct y-intercept
1 point: correct "another solution"
