Answer:
36 cups of water
Step-by-step explanation:
Make a proportion, where x is the number of cups of water needed:
= 
Cross multiply and solve for x:
2x = 72
x = 36
So, 36 cups of water will be needed

Answer:
x = 9
Step-by-step explanation:
For a vertical line, slope is undefined as tan π/2 is undefined. Therefore we cannot express the equation of straight line in terms of it's slope.
For a vertical line, equation is given by, x = c where c is the point on x axis from which the given line passes.
Therefore x = 9 is the equation.
