 Sep 19, 2011 Slope of Line Between Points by: Staff The question:Find the slope of the line passing through (5, 5) and (-4, 5).The answer: 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: (5, 5) and (-4, 5).These points are not listed in the proper order (left to right)They should be listed (-4, 5) and (5, 5) because the slope will be calculated as the change of "y" when x increases. In this case "x" will increase from -4 to 5 (left to right).It is worth plotting the two points so the position of each can be visualized.Open the link shown below to view the two points and the line graph:(1) If your browser is Firefox, click the following link to VIEW ; 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/graph-equation-linear-eq-1-2011-09-19.pngPointsLeft and Right(-4, 5) and (5, 5)(x₁, y₁) and (x₂,y₂)x₁ = -4x₂ = 5y₁ = 5y₂ = 5slope = (y₂ - y₁)/(x₂ - x₁)slope = (5 - 5)/( 5 - (-4))slope = (5 - 5)/( 5 + (-1)*(-4))slope = (5 - 5)/( 5 + 4)Slope = 0/9Slope = 0The final answer to your question is: Slope = 0Thanks for writing.Staff www.solving-math-problems.com
