Best ResponseYou've already chosen the best response.0For two points at (x1,y1) and (x2,y2), respectively, the rate of change is equal to the slope of the shortest possible line segment connecting the two points. This slope can be calculated by the following equation: m = (y2y1)/(x2x1)

Best ResponseYou've already chosen the best response.0you do have enough points to use that equation. [4, 2] is an interval, not a point. They're saying find the slope between the points where x = 4 and x = 2. What is the yvalue when x = 4, and what is it for x = 2?

Best ResponseYou've already chosen the best response.0y= 12 when x= 4, and y= 0 when x= 2

Best ResponseYou've already chosen the best response.0ok. so the points are (4, 12) and (2, 0). \[ROC=\frac{ y _{2}y _{1} }{ x _{2} x _{1}}=\frac{ 0(12) }{ 2(4) }\]
