Front

How do you find the y-intercept from the equation of a line in slope-intercept form?

Back

Set x=0 and solve for y.

Front

What is the general form of a linear equation?

Back

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

Front

How can you determine if a line is increasing or decreasing from its slope?

Back

If the slope (m) is positive, the line is increasing; if negative, the line is decreasing.

Front

What does it mean if the slope of a line is zero?

Back

The line is horizontal.

Front

What does it mean if the slope of a line is undefined?

Back

The line is vertical.
