Graphing Linear Equations

Front

What is the y-intercept of a line?

Back

The y-intercept is the point where the line crosses the y-axis.

Front

What is the x-intercept of a line?

Back

The x-intercept is the point where the line crosses the x-axis.

Front

In the equation y = mx + b, what does 'b' represent?

Back

The 'b' represents the y-intercept of the line.

Front

What does the slope of a line indicate?

Back

The slope indicates the steepness of the line and the direction it goes (rise over run).

Front

How do you find the y-intercept from an equation?

Back

Set x = 0 in the equation and solve for y.

Front

How do you find the x-intercept from an equation?

Back

Set y = 0 in the equation and solve for x.

Front

What is the standard form of a linear equation?

Back

The standard form is Ax + By = C, where A, B, and C are integers.

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers (x, y) that represent a point on a graph.

Front

What does it mean for two lines to be parallel?

Back

Two lines are parallel if they have the same slope and never intersect.

Front

What does it mean for two lines to be perpendicular?

Back

Two lines are perpendicular if the product of their slopes is -1.
