Front

What is the slope of a line?

Back

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

Front

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

Back

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

Front

What is the slope of the line represented by the equation y = 3x + 6?

Back

The slope (m) is 3.

Front

What is the slope of the line represented by the equation y = -x - 6?

Back

The slope (m) is -1.

Front

What does a slope of 0 indicate about a line?

Back

A slope of 0 indicates that the line is horizontal.

Front

What does an undefined slope indicate about a line?

Back

An undefined slope indicates that the line is vertical.

Front

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

Back

This means that for every 2 units the line moves horizontally (run), it moves 3 units vertically (rise).

Front

How do you identify the slope from a linear equation in the form y = mx + b?

Back

The slope (m) is the coefficient of x in the equation.

Front

What is the slope of a line that rises 5 units for every 3 units it runs?

Back

The slope (m) is 5/3.

Front

If a line has a negative slope, what does this indicate about its direction?

Back

A negative slope indicates that the line descends from left to right.
