What is the standard form of a linear equation?

• y = ax + b

• ax + by = c

• y = mx + b

• ax + by = m

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

• The constant term

• The X-intercept

• The slope

• The Y-intercept

If the X term in the standard form equation is negative, what should you do?

• Subtract it from both sides

• Add it to both sides

• Multiply it by -1

• Divide it by -1

In the equation 3x + 6y = 18, what is the next step after moving the X term to the other side?

• Divide everything by 6

• Combine like terms

• Add 3x to both sides

• Subtract 18 from both sides
