2.5-2.9 Review 24/25

Front

What is the meaning of the y-intercept?

Back

The y-intercept is the value of y when x is 0. It represents the initial value in a linear equation.

Front

Which of these represents slope-intercept form?

Back

y = mx + b, where m is the slope and b is the y-intercept.

Front

What is the meaning of the slope?

Back

The slope represents the rate of change of y with respect to x, indicating how much y changes for a unit change in x.

Front

What does a positive slope indicate?

Back

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

Front

What does a negative slope indicate?

Back

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

Front

How do you calculate the slope between two points (x1, y1) and (x2, y2)?

Back

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

Front

What is the formula for the slope-intercept form of a line?

Back

The formula is y = mx + b.

Front

What does the 'm' represent in the slope-intercept form?

Back

The 'm' represents the slope of the line.

Front

What does the 'b' represent in the slope-intercept form?

Back

The 'b' represents the y-intercept of the line.

Front

How can you identify the slope from a graph?

Back

The slope can be identified by the steepness of the line; it is the rise over run.
