What is the slope of the line that passes through the points (-3/2,2) and (1/2,4)???
increase in y = 4-2 = 2
increase in x = 1/2 - -3/2 = 4/2 = 2
dy/dx = m = slope = increase in y/ increase in x = 2/2 = 1
increase in x = 1/2 - -3/2 = 4/2 = 2
dy/dx = m = slope = increase in y/ increase in x = 2/2 = 1
