Unit 3B Test!!- Graphing Linear Functions

Front

What is the definition of slope in a linear function?

Back

The slope (m) of a linear function represents the rate of change of the function, calculated as the change in y divided by the change in x (m = Δy/Δx).

Front

What does a slope of 0 indicate about a line?

Back

A slope of 0 indicates that the line is horizontal, meaning there is no change in y as x changes.

Front

What does an undefined slope indicate about a line?

Back

An undefined slope indicates that the line is vertical, meaning there is no change in x as y changes.

Front

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

Back

Front

What is the y-intercept of a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis, represented as (0, b) in the equation y = mx + b.

Front

Given the equation y = 2x - 5, what is the slope?

Back

The slope (m) is 2.

Front

What is the slope of the line through the points (2,3) and (9,4)?

Back

Front

How do you determine the slope from a table of values?

Back

Calculate the change in y divided by the change in x between two points from the table.

Front

What is the slope of the line represented by the equation y = -4/3x + 2?

Back

The slope is -4/3.

Front

If a line has a slope of 3/4, what does this mean in terms of rise and run?

Back

For every 4 units moved horizontally (run), the line rises 3 units (rise).
