The slope of a line is calculated by dividing the one y portion of the line by one x portion of the line. In this problem we have two points which can indicate us one portion of the y axis and one portion of the x axis. If we have two points of one line, then we can calculate its slope: Point one (x1, y1) Point two (x2, y2) then the slope can be calculated as: m = (y2 - y1)/(x2 - x1)
So lets use our data: Point one (2, 10) Point two (5, 8) then the slope can be calculated as: m = (8 - 10)/(5 - 2<span>) </span>m = -2/3 therefore the slope is negative and is -2/3
