Front

What are the 'a' values for horizontal shrinks (compressions)?

Back

a > 1

Front

How do you find the slope of a line?

Back

Slope = (change in y) / (change in x). If the line is horizontal, the slope is zero.

Front

What does an undefined slope indicate about a line?

Back

An undefined slope indicates a vertical line.

Front

What is the y-intercept of the equation 3x + y = 5?

Back

(0, 5)

Front

Which parent function corresponds to the graph of an absolute value function?

Back

f(x) = |x|

Front

What is the definition of a slope?

Back

The slope is a measure of the steepness of a line, calculated as the ratio of the vertical change to the horizontal change.

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that as x increases, y also increases.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that as x increases, y decreases.

Front

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

Back

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