Slope! -2024

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 change in y (rise) divided by the change in x (run).

Front

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

Back

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

Front

Find the slope of the line that passes through the points (2, 4) and (6, 12).

Back

The slope is 2.

Front

Find the slope of the line that passes through (10, 1) and (5, 2).

Back

The slope is -1/5.

Front

What is the slope of a line passing through (-2, -2) and (4, -3)?

Back

The slope is -1/6.

Front

Which of these represents slope-intercept form? y - y1 = m(x-x1), Ax + By = C, or y = mx + b?

Back

y = mx + b.

Front

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

Back

In the equation y = mx + b, 'm' represents the slope of the line.

Front

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

Back

In the equation y = mx + b, 'b' represents the y-intercept, the point where the line crosses the y-axis.

Front

If a line has a slope of 0, what does that indicate about the line?

Back

A slope of 0 indicates that the line is horizontal.

Front

If a line has an undefined slope, what does that indicate about the line?

Back

An undefined slope indicates that the line is vertical.
