Solve Systems of Equations by Substitution

Solve the following system of equations. What is the point of intersection of the two lines?

y = 2x - 2 and y = 4

• (-3, 4)

• (3, 4)

• (4, 3)

• (4, -3)

How many solutions does the graph have?

• One solution

• No solution

• Infinite solutions

The first step in solving using the substitution method is __________.

• get x by itself
• get y by itself
• get either variable by itself
• add the equations together
