Slope of a line with constant y value

# 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 ?

 Jul 07, 2013 Slope by: Staff 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: --------------------------------------------------------------

 Jul 07, 2013 Slope by: Staff -------------------------------------------------------------- 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 the final answer is: when y = -5 (or any constant value) slope = 0 Thanks for writing.
