How to find the slope of a line given two points Slope of a line Recall A line is the set of points forming a straight path on a plane. Slope The slope of the line through the distinct points first term and is: Try this! 1. Find the slope between (-3, 2) and (3, 7). Answer 2. Find the slope between (-3, 6) and (5, 2). Answer 3. Find the slope between (5, 4) and (5, 2). Answer undefined 4. Find the slope between (-3, 2) and (5, 2). Answer 0 Summary The slope of the line measures the “steepness of the line”. The bigger the absolute value of the slope, the steeper the line is. Positive slope means “rising” line Negative slope means “falling” line Undefined slope means vertical line. Zero slope means horizontal line. Let’s take a quiz! Tell whether the slope of the following are positive, negative, zero or undefined. Red Answerundefined b. Blue Answerpositive c. Purple AnswerNegative d. Green Answer0 2. Determine the slope of the line given its graph a. Answer b. Answer 3. Determine the slope of the line containing each given pair of points. (2,3) and (5, -1) Answer b. (2,3) and (2, -1) Answerundefined c. (4,-1) and (-2, -1) Answer0
