Topic 2 Part 2 Review

Front

What is the rate of change?

Back

The rate of change is a measure of how much a quantity changes in relation to another quantity, often expressed as change in y over change in x.

Front

What are the different ways to find the rate of change?

Back

1. Change in y over change in x 2. Rise over run 3. Subtract y coordinates over subtract x coordinates 4. All of the above

Front

What does a y-intercept represent on a graph?

Back

The y-intercept is the point where the graph intersects the y-axis, indicating the value of y when x is zero.

Front

What is a proportional relationship in a graph?

Back

A proportional relationship is represented by a straight line that passes through the origin (0,0).

Front

How can you determine if two lines have the same rate of change?

Back

If the slopes of the two lines are equal, they have the same rate of change.

Front

What does the slope of a line represent?

Back

The slope represents the rate of change of the dependent variable (y) with respect to the independent variable (x).

Front

What is the formula for calculating slope?

Back

Slope (m) = (change in y) / (change in x) = (y2 - y1) / (x2 - x1).

Front

What does it mean if a graph is linear?

Back

A linear graph is one that forms a straight line, indicating a constant rate of change.

Front

What is the significance of the coordinates (0, -2) on a graph?

Back

The coordinates (0, -2) indicate the y-intercept, meaning the graph crosses the y-axis at -2 when x is 0.

Front

What does it mean for a line to be curvy on a graph?

Back

A curvy line indicates a non-linear relationship, where the rate of change is not constant.
