step-by-step explanation:

distance formula is d=√(x2-x1)^2   +   (y2-y1)^2

choice b is correct

step-by-step explanation:

we have been given the following system of linear inequalities;

we are required to graphically determine the solution to these system of inequalities. using a graphing tool, the solution is as shown in the attachment below;
