What is the equation of a vertical line that passes through a point?

Back

The equation of a vertical line is in the form x = a, where 'a' is the x-coordinate of the point.

Front

What is the equation of a horizontal line that passes through a point?

Back

The equation of a horizontal line is in the form y = b, where 'b' is the y-coordinate of the point.

Front

What does it mean for a line to have an undefined slope?

Back

A line has an undefined slope if it is vertical, meaning it goes straight up and down.

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0.

Front

How do you identify a vertical line on a graph?

Back

A vertical line is identified by a constant x-value, meaning it does not change as y changes.

Front

How do you identify a horizontal line on a graph?

Back

A horizontal line is identified by a constant y-value, meaning it does not change as x changes.

Front

What is the general form of a linear equation?

Back

The general form of a linear equation is y = mx + b, where m is the slope and b is the y-intercept.

Front

What is the significance of the slope in a linear equation?

Back

The slope indicates the steepness and direction of the line; a positive slope rises, while a negative slope falls.

Front

What does the y-intercept represent in a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis, represented by the value of b in y = mx + b.

Front

What is the equation of a line with a slope of 0?

Back

The equation of a line with a slope of 0 is y = b, where b is a constant.
