Question 1205787
here's the graph.]


<img src = "http://theo.x10hosting.com/2024/012401.jpg">


any point on that line and to the right and above it is valid.


for example:


the point (0,8) is valid because 0 * 24 + 8 * 9 = 72 which is >= 72.


the point (2,2) is not valid because 2 * 24 + 2 * 9 = 66 which is not >= 72.


you can look at the points that are on your graph and determine very quickly whether they are valid based on whether they are on the line or to the right and above the line.


you can also evaluate each point by replacing the x value of that point and the y value of that point with the values of x and y obtained from the equation at that point and determine whether the value of y is greater than or equal to 72.
