Front

What is the formula to calculate the slope between two points?

Back

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

Front

Given the points (2, −7) and (−1, 6), what is the slope?

Back

-13/3

Front

What does a greater rate of change indicate in a graph?

Back

A steeper slope.

Front

What inequality does the number line graph with a closed circle at 3 represent?

Back

x ≥ 3

Front

What is the vertical line test used for?

Back

To determine if a graph represents a function.

Front

If a graph does NOT pass the vertical line test, what does that mean?

Back

It means that the graph does not represent a function.

Front

In the equation y = -3x + 7, what is the y-intercept?

Back

7

Front

What is the definition of a function?

Back

A relation where each input has exactly one output.

Front

What does the slope of a line represent?

Back

The rate of change of y with respect to x.

Front

How do you identify the y-intercept from an equation in slope-intercept form?

Back

It is the constant term (b) in the equation y = mx + b.
