Front

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

Back

Set x = 0 and solve for y.

Front

What does the slope of a line represent in a linear equation?

Back

The rate of change of y with respect to x.

Front

What is the slope of the line represented by the equation y = 2x + 5?

Back

2

Front

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

Back

If the slope is positive, the line is increasing; if negative, it is decreasing.

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.
