Semester 1 Final Review '24

Front

What is absolute value?

Back

The distance of a number from zero.

Front

Identify the error in the equation: 19 - 2k = 3k - 1. What should be done instead of adding 3k?

Back

They should subtract 3k.

Front

Is the function f(x) = 3x - 9 linear or nonlinear?

Back

Linear Function.

Front

Calculate f(5) if f(x) = 3x - 9.

Back

f(5) = 6.

Front

What is the slope of the line represented by the equation y = (4/3)x + b?

Back

4/3.

Front

Define a linear function.

Back

A function that graphs to a straight line and has a constant rate of change.

Front

What is the formula for finding the slope between two points (x1, y1) and (x2, y2)?

Back

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

Front

What does it mean for a function to be nonlinear?

Back

It means the function does not graph to a straight line and has a variable rate of change.

Front

What is the multiplicative inverse of a number?

Back

The number that, when multiplied by the original number, results in 1.

Front

How do you find the y-intercept of a linear equation in the form y = mx + b?

Back

The y-intercept is the value of b.
