Graphing Two-Variable Linear Equations

What is the first step in graphing the linear equation 5x + 2y = 20?

• Solving for y

• Plotting points on the graph

• Setting up a table of values

• Drawing the line

What do you get when you subtract 5x from both sides of the equation 5x + 2y = 20?

• 2y = 20 + 5x

• 2y = 20 - 5x

• 5x = 20 - 2y

• 5x = 20 + 2y

What is the simplified form of y when you divide both sides of 2y = 20 - 5x by 2?

• y = 10 - 5/2x

• y = 10 + 5x

• y = 10 - 5x

• y = 10 + 5/2x
