Graphing Standard Form Linear Equations

What is the standard form of a linear equation?

• ax + by = c

• y = mx + b

• ax - by = c

• y = ax + b

In the slope-intercept form y = mx + b, what does 'm' represent?

• The y-intercept

• The constant term

• The slope

• The x-intercept

What is the first step in converting a standard form equation to slope-intercept form?

• Find the x-intercept

• Graph the y-intercept

• Move the ax term to the left side

• Divide everything by b

• 0

What is the second step in converting a standard form equation to slope-intercept form?

• Move the ax term to the left side

• Divide everything by b

• Graph the y-intercept

• Find the x-intercept
