Solving Systems of Equations

What is the primary method used to solve the system of equations in this lesson?

• Substitution

• Elimination

• Graphing

• Matrix method

What is the first equation presented in the system?

• Y = 2x + 3

• Y = 2x - 3

• Y = -2x - 3

• Y = -2x + 3

What is the second equation presented in the system?

• Y = 2/3x + 5

• Y = -2/3x - 5

• Y = -2/3x + 5

• Y = 2/3x - 5

What does the point of intersection of the two graphed equations represent?

• The y-intercept

• The slope

• The solution to the system

• An unrelated point

What form are both equations in, which makes them easy to graph?
