Slope Intercept Form Review

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 over run).

Front

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

Back

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

Front

What does 'm' represent in the slope-intercept form equation y = mx + b?

Back

'm' represents the slope of the line.

Front

What does 'b' represent in the slope-intercept form equation y = mx + b?

Back

'b' represents the y-intercept, the point where the line crosses the y-axis.

Front

What is the slope of the line that passes through the points (2, 4) and (6, 12)?

Back

The slope is 2.

Front

If the slope is 1/2 and the y-intercept is (0, -4), what is the equation in slope-intercept form?

Back

y = 1/2x - 4.

Front

What is the equation of the line in slope-intercept form that passes through (-1, -2) with a slope of -3?

Back

y = -3x - 5.

Front

What does a negative slope indicate about a line?

Back

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

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that the line is increasing from left to right.

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0.
