Unit 4 – Item 2
Model the following systems of equations:

y = 2x + 4
y = 2x + 1

  • 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.

Unit 4 – Item 6
Describe and correct the error in solving the system of linear equations.
4x + y = 10
5x – 3y = 6

Step 1:
4x + y = 10
y = -4x + 10

Step 2:
4x + (-4x + 10) = 10
10 = 10
