Question 57282: Can someone help me give the coordiates of the point on the graph I will try to explain to you the best I can?
I have the x-axis and y-axis. Where they meet in the middle going right of y the bar numbers go 1, 2, 3, 4, 5 and on the right side of the y-axis from the middle of y and on the left side it goes -1, -2, -3, -4, -5
The point that I need to coordinate is on the bottom right of x and right of the y-axis bar, 5 bars down and 4 bars over from the y-axis bar.
Thanks so much if you can help.

(R) is above the x-axis and on the left side of y 3 bars up and one overfrom y
(S) is above the x-axis on the right side of y and is two bars up and 3 bars over from y.
(T) is below x on the right side of y and 3 bars down and 3 bars over from y
(U) is on the y-axis below the x-axis and two bars down.
(v) is on the left side of y-axis and 4 bars down and two bars over from y.
I would appreciate all the help you can give.

Question 57629: Can someone help me draw this graph since I have to put it through the computer and not on paper?
I need to do a straight-line graph.
We start with a birthday gift check of $500 where we put in the bank as the first deposit and then add every month pocket money of $100 per month to it. My balance B as a function of months elaspsed will be B= 500 + 100*N=1
after 2 months N=2. B=500 + 2*100=700, etc
If you plot N on the x axis starting from N=0 to say 12 months and Bon Y axis it will be a straight line.
Could you draw the graph and show me the equation and how it would look.
I am lost.

Question 57620: Can someone help me on this problem?
I need to graph a straight-line graph on a real-life situation. I used a situation where if a person would go to sleep after the 11:30 p.m. news and wake-up every day at 7:30 a.m. being 8 hours a day, seven days a week. If that would be one variable what would the second one be and how would I write up the equation or inequality and draw a graph? I have to send it through the computer and can't write it on paper.
Can someone help me out there? I have to send it through tomorrow.
Need help.

: Could someone help me on this problem please?
I need to draw the appropriate graph for the following problem:
A small firm produces both AM and AM/FM car radios. The AM radios take 15 h. to produce, and the AM/FM radios take 20 h. The number of production hours is limited to 300 h. per week. The plant's capacity is limited to a total of 18 radios per week, and existing orders require that at least 4 AM radios and at least 3 AM/PM radios be produced per week. Write a system of inequalities representing this situation. Then, I need a raph of the feasble region given these conditions, in which x is the number of AM radios and y the number of AM/FM radios.
