The function y=F(x) is graphed below Plot a line segment connecting the points on f where x=0 and x=1. Use the line segment to determine the average rate of change of the function f(x) on the interval

Points j and k plotted on the coordinate grid are two vertices of rectangle jklm rectangle jklm has an area of 7 square units point j is located at 2,1 and point k is located at -5,1 each vertex of the rectangle is located at a point that has integer coordinates. what is the perimeter of rectangle jklm? (need answer asap)
