Multiple Choice

When points lie in a straight line on a graph this is called what type of relation?

• Quadratic

• Cubic

• Circular

• Linear

Multiple Choice

Ax + By = C

is what type of form of a linear equation?

• Slope-Intercept Form

• Standard Form

• Point-Slope Form

Multiple Choice

What can we do to get this to standard form?

2x + 3y - 7 = 0

• Divide by 2

• Add 7

• Multiply by 3

Multiple Choice

What can we do to get this to standard form?

2x = 7 - 2y

• Divide by 2 to both sides

• Subtract 7 to both sides

• Add 2y to both sides
