What are the differences between positive and negative slope zero and undefined slopes?

What are the differences between positive and negative slope zero and undefined slopes?

The slope of a line can be positive, negative, zero, or undefined. A horizontal line has slope zero since it does not rise vertically (i.e. y1 − y2 = 0), while a vertical line has undefined slope since it does not run horizontally (i.e. x1 − x2 = 0). because division by zero is an undefined operation.

How do you know if a graph is positive or negative?

A function is positive when the y values are greater than 0 and negative when the y values are less than zero. Here’s the graph of a function: This graph is positive when x is less than 2 and negative when x is greater than 2.

What are the differences between zero and undefined slopes?

Summary: 1.An undefined slope is characterized by a vertical line while a zero slope has a horizontal line. 2. The undefined slope has a zero as the denominator while the zero slope has a difference of zero as a numerator.

What does a positive line look like on a graph?

If a line has a positive slope (i.e. m > 0), then y always increases when x increases and y always decreases when x decreases. Thus, the graph of the line starts at the bottom left and goes towards the top right.

Is a zero slope positive or negative?

Classifying the Slope Positive slope means the graph rises or goes uphill. Negative slope means the graph falls or goes downhill. Zero slope means the line is flat or horizontal.

Is a slope of 0 positive or negative?

Negative slope. A slope of zero means that y is constant no matter the value of x. Graphically, the line is flat; the rise over run is zero.

Is the slope Positive negative zero or undefined?

Positive slope means the graph rises or goes uphill. Negative slope means the graph falls or goes downhill. Zero slope means the line is flat or horizontal. Undefined slope means the line is vertical.
