When you graph a linear equation, the graph will be straight line.

• True
• False

The first step in graphing a linear equation is to make a table to find your x and y values.

• True
• False

The equation y = mx + b is called an equation 

• in standard form
• in slope-intercept form
• in expression form
• none of the answers

The equation y = 2x + b is 

• A non-linear equation and if you graph it will not form a straight line
• A linear equation because the equation is in slope intercept form. The graph will form a straight line.

A dog walker earns $10 plus $3 per dog. What equation represents this model? 

• y=3x + 10
• y=10x + 3
• y=13x
• y=10x - 3

Which equation matches the table?

• y = x + 5
• y = 5x
• y = x - 5
• x = y - 5
