Coordinate Plane and Slope Review

Front

What is the slope of a line?

Back

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

Front

What does a positive slope indicate?

Back

A positive slope indicates that as x increases, y also increases, resulting in an upward trend.

Front

What does a negative slope indicate?

Back

A negative slope indicates that as x increases, y decreases, resulting in a downward trend.

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is zero.

Front

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined.

Front

What is slope-intercept form?

Back

Slope-intercept form is a way of writing the equation of a line as y = mx + b, where m is the slope and b is the y-intercept.

Front

How do you find the y-intercept from an equation?

Back

To find the y-intercept, set x to 0 in the equation and solve for y.

Front

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

Back

The 'b' in the slope-intercept form y = mx + b represents the y-intercept, the point where the line crosses the y-axis.

Front

What is the first quadrant in the coordinate plane?

Back

The first quadrant is the section of the coordinate plane where both x and y values are positive.

Front

How do you convert an equation to slope-intercept form?

Back

To convert to slope-intercept form, solve for y in terms of x.
