Understanding Systems of Equations

What type of equations are being solved in this tutorial?

• Two linear equations

• Two quadratic equations

• A linear and a quadratic equation

• A linear and a cubic equation

What is the purpose of using the 'y equals' screen on the calculator?

• To find the derivative of the equations

• To enter the equations for graphing

• To solve the equations directly

• To calculate the area under the curve

How many points of intersection are visible when the system is graphed?

• None

• Three

• Two

• One

What is the first step in finding the exact point of intersection using the calculator?

• Relocate the cursor near the intersection

• Select the 'trace' function

• Enter the equations again

• Change the graph settings

What are the exact coordinates of the second point of intersection?

• (x = 0, y = 0)

• (x = 1, y = 1)

• (x = 2, y = 4)

• (x = -3, y = 9)
