Answer:
We know for our problem that Rachel makes $10 per hour. Since
represent the number of hours that she works, 
will be the total amount that she will make for working hours. We also know that she sells bracelets for $5 each. Since 
represents the number of of bracelets that she sells, 
will be her total revenue for selling bracelets. We also know that she needs to earn at least $200 a week to cover her expenses, so the sum of and must be equal or greater than 200:
We can conclude that <span>the graphs that shows the inequality that represents this situation, with its solution region shaded is:</span>

First, we'll find the slope of the new line. The first line has a slope of . Take the negative reciprocal of this (Flip the numerator and denominator, then multiply by
) to get
for the new slope.
Then, we'll use the point-slope form to make the new equation, where is the slope and
is a point on the line:
