When any two points of a line are substituted into the slope formula the slope of . the line should be the answer. In this case, when P1 and P2 are substituted into . the slope formula the answer should be 1/3. Since P. 1 = (2, -1) and P2 = (11, 2) then x1 = 2, x2 = 11, y1 = -1 and y2 = 2 then: () 21 21 1 3 211 11 2 3 31 93 11 33 YY XX − ...
The slope of a line describes the steepness of the line. The slope can be found by using two points on a line (, )x11y and (, )x22y along with the following formula: Slope (m) = 21 21 y y x x − − = (vertical change) (horizontal change) Example 2: Find the slope of the line containing the points A(–2, –6) and B(3, 5). The slope of the ...
