Slope of a line with constant y value








































Constant y value

The slope of a straight line is equal to the change in the y value divided by the change in the x value.

What is the slope of the line where y = -5 ?

Answer

Part I
When the y value is a constant, this means that the value of y is the same, regardless of the value of x.

This can be plotted as follows:

Part II


In this case y₂ and y₁ have the same value: y


The x-y coordinates of any two points are: (x₁, y) and (x₂, y) .

The slope will be calculated as the change of “y” when x increases. In this case “x” will increase from x₁ to x₂ (left to right).

slope = (y₂ - y₁)/(x₂ - x₁)

slope = (y - y)/(x₂ - x₁)

slope = (0)/(x₂ - x₁)

slope = 0


Slope of a line = rise over run




the final answer is:

when y = -5 (or any constant value)


slope = 0
