Front

Define y-intercept.

Back

The y-intercept is the point where the line crosses the y-axis, represented by the value of y when x=0.

Front

Define slope.

Back

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

Front

Back

It represents the slope-intercept form of a linear equation, where m is the slope and b is the y-intercept.

Front

If the slope of a line is 2, what does this mean?

Back

It means that for every 1 unit increase in x, y increases by 2 units.

Front

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

Back

Use the formula: slope = (y2 - y1) / (x2 - x1).

What does a slope of 0 indicate about a line?

Back

A slope of 0 indicates that the line is horizontal.
