Applying the expression for get the slope of a line, the slope was found to be 2/3Slope and InterceptsGiven Datax1 = 4y1 = 8x2 = 1y2 = 6Applying the expression for finding slope we haveSlope of line = (y2-y1)/(x2-x1)Substituting our data we haveSlope of line = (6-8)/(1-4)Slope of line = (-2)/(-3)Slope of line =2/3
