What is the definition of an undefined slope?

Back

An undefined slope occurs when a line is vertical, meaning it goes straight up and down. The slope is calculated as the change in y divided by the change in x, and since the change in x is zero, the slope is undefined.

What is the definition of a positive slope?

Back

A positive slope indicates that as the x-value increases, the y-value also increases. It is represented by a line that rises from left to right.

Front

What is the definition of a negative slope?

Back

A negative slope indicates that as the x-value increases, the y-value decreases. It is represented by a line that falls from left to right.

Front

What does a zero slope indicate about a line?

Back

A zero slope indicates that the line is horizontal, meaning it does not rise or fall as it moves from left to right.

Front

How do you convert a fraction to a decimal?

Back

To convert a fraction to a decimal, divide the numerator by the denominator.

Front

What is the formula for finding the slope between two points (x1, y1) and (x2, y2)?

Back

The slope (m) is calculated using the formula m = (y2 - y1) / (x2 - x1).

What is the significance of the point (1, 3) in a system of equations?

Back

The point (1, 3) is the solution to the system of equations, meaning it satisfies all equations in the system.
