Linear Functions Vocabulary

What is the definition of Arithmetic Sequences (2.1)?

• A number sequence formed by adding a fixed number to each previous term to find the next term.

• A number sequence formed by multiplying each term by a fixed number to get the next term.

• A sequence where each term is the square of its position in the sequence.

• A sequence where the difference between terms alternates between positive and negative.

Which of the following is an example of an Arithmetic Sequence?

• 2, 7, 10, 13, ...

• 1, 2, 4, 8, ...

• 3, 6, 12, 24, ...

• 5, 10, 20, 40, ...

What is a Linear Equation (2.1)?

• An equation whose graph is a line.

• An equation whose graph is a circle.

• An equation whose graph is a parabola.

• An equation whose graph is a triangle.

Which of the following is the slope-intercept form of a linear equation?

• y = mx + b

• y = m(x - x1)

• Ax + By = C

What does the Rate of Change (2.1) describe in a linear equation?

• A rate that describes how one quantity changes in relation to another quantity.

• The value of the y-intercept in a linear equation.

• The maximum value reached by the function.

• The number of solutions to the equation.

What is the formula for Slope (2.1)?

• m = (y2 - y1) / (x2 - x1)

• m = (x2 - x1) / (y2 - y1)

• m = (y1 + y2) / (x1 + x2)

• m = (x1 - x2) / (y1 - y2)
