I assume we are finding the slope of the line. It is positive since it runs from the lower left to the upper right, so forget B and D. Since slope is defined as rise over run, in order to get from one point on the line that goes through right where the grids meet to another point that goes through right where the grids meet we count up 1 unit and then to the right 6 units. This is a slope of 1/6.
Margaret has a monthly clothes budget of $50. This implies that she can spend a maximum of $50 on clothes and therefore the maximum value of the domain is 50 to or it can also be said that the domain is all values of domain from 0 to 50.
