Using the data below derived from Problem 7.1,

(1) Graph the inequality constraints by first solving each for x2 in terms of x1.

(2) Regraph and darken in the feasible region.

(3) Compute the slope of the objective function. Set a ruler with this slope, move it to the point where it is tangent to the feasible region, and construct a dashed line.

(4) Read the critical values for x1 and x2 at the point of tangency, and evaluate the objective function at these values.
