What is the slope of a line?

Back

The slope of a line is a measure of its steepness, typically represented as 'm' in the slope-intercept form of a linear equation (y = mx + b). It is calculated as the change in y divided by the change in x (rise/run).

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that as the x-values increase, the y-values decrease, meaning the line descends from left to right.

Front

What is the origin in a coordinate plane?

Back

The origin is the point where the x-axis and y-axis intersect, represented as (0,0).

Front

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

Back

The slope (m) is calculated using the formula m = (y2 - y1) / (x2 - x1).

Front

What is the x-axis?

Back

The x-axis is the horizontal line in a coordinate plane where y = 0.

Front

What is the y-axis?

Back

The y-axis is the vertical line in a coordinate plane where x = 0.

Front

What does an undefined slope mean?

Back

An undefined slope occurs when a line is vertical, meaning it goes straight up and down, and the change in x is zero.

Front

What is a zero slope?

Back

A zero slope indicates a horizontal line, where the change in y is zero as x changes.

Front

What is the slope of the line represented by the equation y = 6x + 1?

Back

The slope of the line is 6.

Front

What is the slope of the line represented by the equation y = -2x + 3?

Back

The slope of the line is -2.
