18. Manufacturers often package products in a way that uses the least amount of material One measure of the efficiency of a pack
age is the ratio of its surface area to its volume. The smaller the ratio, the more efficient the packaging. A company makes a cylindrical can to hold popcorn. The company is designing a new can with the same height h and twice the radius r of the old can. a. Write an expression for the efficiency ratio where S is the surface area of the can and Vis the volume of the can. b. Find the efficiency ratio for each can. c. Did the company make a good decision by creating the new can? Explain

As you may realize, the equation y=-7/4x-2 is already formatted in slope-intercept form, which means that its slope is represented by the "x" coefficient, that is, -7/4.
Lines that are parallel share identical slopes, therefore a line parallel to this would also maintain a slope of -7/4, which would go through the point (4,2),
