Module 5 Flashcardizz - Questions

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, usually represented as 'm'. It is calculated as the ratio of the rise (change in y) over the run (change in x).

Front

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

Back

The slope (m) can be found using the formula: m = (y2 - y1) / (x2 - x1).

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that as the x-value increases, the y-value also increases, meaning the line rises from left to right.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that as the x-value increases, the y-value decreases, meaning the line falls from left to right.

Front

What does a slope of zero mean?

Back

A slope of zero means the line is horizontal, indicating that there is no change in y as x changes.

Front

What does an undefined slope mean?

Back

An undefined slope occurs in vertical lines where the change in x is zero, indicating that the line does not have a slope.

Front

If a line has a slope of 3/2, what does this mean?

Back

A slope of 3/2 means that for every 2 units moved horizontally to the right, the line rises 3 units vertically.

Front

What is the slope of the line represented by the equation y = 4x + 1?

Back

The slope of the line is 4, which means it rises 4 units for every 1 unit it moves to the right.

Front

How do you determine if a slope is positive, negative, or zero from a graph?

Back

If the line rises from left to right, the slope is positive. If it falls, the slope is negative. If it is horizontal, the slope is zero.

Front

What is the slope of a line that is vertical?

Back

The slope of a vertical line is undefined because the change in x is zero.
