The graph that best represents the function in this case, will be given by evaluating x in the function sometimes to build the number of points needed to describe the straight line. In this case, the graphic is shown in the attached file
x= <span> 0 <span>1 2 3 4 5 6 7 8 9 <span> 10
</span></span></span><span><span> F(x)= 6 4 </span> 2 0 -2 -4 -6 -8 -10 -12 -14
</span><span>zero is at x = 3!!!</span>
x= <span> 0 <span>1 2 3 4 5 6 7 8 9 <span> 10

Solution:
As per the problem we have
Rectangle JKLM was plotted in the coordinate plane and side segment JK had a slope of 3 fifths.
As we know the sides of the rectangle are always perpendicular to each other.
We also know that when two straight lines are perpendicular to each other then the product of their slopes gives negative one.
