Math, microeconomics or criminal justice
3x + 4y > 20
4y > -3x + 20
y > (-3/4)x + 5 graph the line with slope =-3/4 and y intercept = 5 (0,5)
x intercept = 20/3 or the point (6 2/3, 0)
plot the x and y intercepts and connect them with a straight line, Make the line dotted to indicate the inequality does not include the line itself. shade in above the line
3y-18> x
3y> x + 18
y > x/3 + 6. 6 is the y intercept or the point (0,6) x intercept is -18 or the point (-18,0)
plot the x and y intercepts, connect then with a straight dotted line and shade in everything above the line
doubly shade in everything in the area where both shaded areas coincide, that's the solution to the problem
