Standard Form and Intercepts Practice

Which of these represents the standard form of a linear equation?

• y - y₁ = m(x - x₁)

• Ax + By = C

• y = mx + b

Find the standard form of y = 2x + 9

• -2x - y = 9

• 2x - y = -9

• 2x + y = 9

• -2x + y = -9

Which of the following are written in standard form?

• y=3x-5

• 3x+16=5y

• 2/3 x + 9/13 y = 21

• 5x+7y=-12

What's the definition of x-intercept?
