Question 5:Diagram 3 shows a shaded region which satisfies three inequalities.State all the inequalities.Solution: Shaded region above the solid line, y= 3 2  is y≥ 3 2 . At y-intercept, c=6. x-intercept =6 gradient, m=− 6 6 =−1 y=mx+c y=−x+6 ∴Shaded region below the solid line is y≤−x+6. At origin, y-intercept c=0, gradient, m= 1.5−0 0.5−0 =3 y=mx+c y=3x+0 y=3x ∴Shaded region below the … Read more
