2024 Fall Final Exam Review II.

Front

What does the y-intercept of a linear graph represent?

Back

The y-intercept represents the starting value of the dependent variable when the independent variable is zero.

Front

What is the significance of the x-intercept in a linear equation?

Back

The x-intercept is the point where the graph crosses the x-axis, indicating the value of the independent variable when the dependent variable is zero.

Front

How do you determine if two lines are parallel?

Back

Two lines are parallel if they have the same slope.

Front

What is the slope of a line?

Back

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

Front

What does the range of a function represent?

Back

The range of a function is the set of all possible output values (y-values) that the function can produce.

Front

How do you find the slope of a line given its equation in standard form?

Back

To find the slope from the standard form Ax + By = C, rearrange to slope-intercept form (y = mx + b) where m is the slope.

Front

What is the relationship between the slopes of perpendicular lines?

Back

The slopes of perpendicular lines are negative reciprocals of each other.

Front

What does it mean for a line to be horizontal?

Back

A horizontal line has a slope of 0 and runs parallel to the x-axis.

Front

What does it mean for a line to be vertical?

Back

A vertical line has an undefined slope and runs parallel to the y-axis.

Front

How can you identify the x-intercept from a linear equation?

Back

To find the x-intercept, set y to 0 and solve for x.
