What is y > 2x - 4 and 6x +3y < 9

you can make a table of values using any intergers and as many as you need in this case I chose 0,1,2 then you replace them in your actual equation and find the values of y.finally plot.

after plotting the points you shade the unwanted region(the sign will direct you) in this case the wanted region is y>.so you shade the less than area.

for the second one you make the equation simpler

6x+3y<9

3y<-6x+9

and also make a table of values,replace were there's x and plot

I hope this helps!

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).
