What is the correct solution set for the following graph? graph showing two lines, labeled a and b, one atop the other {point in Quadrant I} {point in Quadrant II} {point in Quadrant IV} {infinite set of points on the line}

Graph the line that represents a proportional relationship between d and t with the property that an increase of 33 units in t corresponds to an increase of 44 units in d. what is the unit rate of change of dd with respect to t? (that is, a change of 11 unit in t will correspond to a change of how many units in d? )
