# Slope of Linear Equation

the variables in linear equations have no exponents

the slope of linear equation is the change in y values divided by the change in x values

x - 3 = -5 what is the slope?

Answer: x - 3 = -5 x - 3 + 3 = -5 + 3 x + 0 = -2 x = -2 x always = -2, regardless of the value of y You can view a graph of x = -2 by opening the following link: (1) If your browser is Firefox, click the following link to VIEW the graph; or if your browser is Chrome, Internet Explorer, Opera, or Safari (2A) highlight and copy the link, then (2B) paste the link into your browser Address bar & press enter: Use the Backspace key to return to this page http://www.solving-math-problems.com/images/slope-vertical-line-01-2012-02-27.png slope = “rise” over “run”, or “rise” DIVIDED BY “run” slope = (change in “y” values)/(change in “x” values) slope = (y₂ - y₁)/(x₂ - x₁) The x-y coordinates of the two points are: (-2, y₁) and (-2, y₂) . The slope will be calculated as the change of “y” when x increases. In this case “x” does not change, regardless of the value of y. slope = (y₂ - y₁)/(-2 – (-2)) slope = (y₂ - y₁)/(-2 + 2) slope = (y₂ - y₁)/ 0 slope = undefined (or ±∞) >>>the final answer is: slope = vertical = undefined (or ±∞) Thanks for writing.
