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 goes down from left to right.

What does a positive slope indicate about a line?

Back

A positive slope indicates that as the x-values increase, the y-values also increase, meaning the line goes up from left to right.

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

Back

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

Front

If a line has a slope of -1/2, what does this mean?

Back

For every 2 units you move to the right (positive x-direction), you move 1 unit down (negative y-direction).

What does a slope of 1 represent?

Back

A slope of 1 means that for every 1 unit increase in x, there is a 1 unit increase in y, resulting in a 45-degree angle line.

What is the slope-intercept form of a line?

Back

The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.
