3.5 Thembi makes a profit of R30 on average on a bouquet of flowers. Based on (4) the expenses in week 3, decide whether Thembi will be able to break even for that week if she sells 170 bouquets for the week? Use calculations to motivate your answer by showing by how many bunches she exceeds/ is short of the break even target.

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
