Writing Equations in Standard Form

Writing in Standard Form

Learning Objective: I can write equations in standard form.

Ax + By = C

Standard Form

Ax + By = C

• A is a coefficient that is an integer.

• B is a coefficient that is an integer.

• C is an integer.

Manipulate an equation algebraically in order to put it in STANDARD FORM

• Get both variables with their coefficients on ONE SIDE of the equal sign.

• Get the constant alone on the opposite side of the equal sign.

• Undo operations in order to move terms from one side of an equation to the other.

Multiple Choice

What is standard form of a line?

• y = mx + b

• Ax + By = C

• y - y1 = m(x - x1)

• y = Ax + By

Multiple Choice

Which equation is written in STANDARD form?

• y = 1/2x + 2
• y - 3 = -5(x + 2)
• -7x + 2y = 9
• 3x + 2 = y

Multiple Choice

Write the standard form of the equation for the line:

4y = x + 4

• x + 4y = 8

• -x + 4y = -16

• y = x + 16

• 4y + x = 8
