Front

What is the y-intercept?

Back

The y-intercept is the point where a line crosses the y-axis. It is represented as the value of y when x = 0.

Front

What is the slope?

Back

The slope is a measure of the steepness of a line, calculated as the change in y divided by the change in x (rise over run).

Front

Find the y-intercept from the graph.

Back

The y-intercept is the value of y at the point where the line crosses the y-axis.

Front

What is the slope in the equation y = 2x + 3?

Back

The slope is 2, which indicates that for every 1 unit increase in x, y increases by 2 units.

Front

Find the slope of the line.

Back

The slope can be calculated using the formula (y2 - y1) / (x2 - x1) using two points on the line.

Front

What does a positive slope indicate?

Back

A positive slope indicates that as x increases, y also increases, showing an upward trend.

Front

What does a negative slope indicate?

Back

A negative slope indicates that as x increases, y decreases, showing a downward trend.

Front

What is the formula for slope?

Back

The formula for slope (m) is m = (y2 - y1) / (x2 - x1).

Front

How do you find the slope from a graph?

Back

To find the slope from a graph, select two points on the line, determine the rise (change in y) and run (change in x), and apply the slope formula.

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0, indicating no change in y as x changes.
