Does the distance a person kicks a soccer ball effect how well they will do on their math test?

What is the dependent variable?

• How far they kick the soccer ball

• Who the person is

• How well they do on the math test

• Type of soccer ball.

For the function {(0,1), (1,-3), (2,-4), (-4,1)}, write the domain.

Remember: Domain is x

(x,y)

• D: {1, -3, -4,}

  R: {0, 1, 2, -4}

• D:{0, 1, 2, -4}

  R:{1, -3, -4}

• D:{0, 1, 2, 3, 4}

  R:{1, -3, -4}

Is this a function or not a function?

• Function

• Not a Function

Combine like terms

• 5x + 10y

• 5x + 4y

• 5x - 4y

• 5x -10y

Which of these represents point-slope form of a linear equation?

• y - y₁ = m(x - x₁)

Which of these represents slope-intercept form of a linear equation?

• y - y₁ = m(x-x₁)

• y = mx + b

• Ax + By = C
