Because Vicky spends 1 hour reviewing each old chapter and 1.5 hours learning each new chapter, the total number of hours she spends each week can be represented by the equation:
Total hours = 1x + 1.5y.
Given that Vicky spends at least 10 hours per week studying, we can create the inequality:
1x + 1.5y ≥ 10.
This inequality represents Vicky's weekly study time. The graph that represents this inequality would be a line on a graph where the area above and to the right of the line would be shaded to indicate all the possible values of x and y that satisfy the inequality.
