Front

Identify any outliers in the following data set: (15, 10), (15, 10), (15, 10), (15, 10), (20, 15)

Back

Outlier: (20, 15)

Front

What is the x-intercept of the linear equation -3x + 2y = -24?

Back

(8, 0)

Front

Calculate the slope from the following table: (1, 2), (2, 6), (3, 10)

Back

Slope: 4/1

Front

What type of function is represented by the equation y = x^2 + 3?

Back

Quadratic function

Front

Is the function represented by the equation y = 2x + 3 Linear or Nonlinear?

Back

Linear

Front

Define an outlier in a data set.

Back

An outlier is a data point that differs significantly from other observations.

Front

What is the standard form of a linear equation?

Back

Ax + By = C, where A, B, and C are constants.

Front

How do you find the slope of a line given two points (x1, y1) and (x2, y2)?

Back

Slope (m) = (y2 - y1) / (x2 - x1)

Front

What is the definition of a linear function?

Back

A function that graphs to a straight line, represented by the equation y = mx + b.

Front

What is the difference between linear and nonlinear functions?

Back

Linear functions have a constant rate of change; nonlinear functions do not.
