Question 58769: I just don't get this at all, and I need to pass this class, HELP!!!!!
I need to find the missing coordinates for this one
y= -x+4
I have to graph each equation and plot atleast 5 points for each one:
x+4y=5
Demand Equation- Helen's Health Foods usually sells 400 cans of ProPac Muscle Punch per week. After experiencing with prices for some time, Helen has determined that the weekly demand can be found by using the equation: d=600-40p, where d is the number of cans and p is the price per can.
a) Will Helen sell more or less Muscle Punch if she raises her prices from $5?
b) What happens to her sales every time she raises her price by $1?
The line through ( -2,5) with slope of -1
Find the slope and y-intercept for each line that has a slope and y-intercept.
x+2y=3
Write each equation in standard form using only integers
y= 4/5x+2/3
Draw the graph of each line using its y-intercept and its slope
2x=y=0
Find the equation of the line that goes through the given point and has the given slope. Write the answer in slope intercept form
(-1,-5), -8
Find the equation of each line in the form y=mx=b if possible
The line through the origin that is perpendicular to the line through (-3,0) and (0, -3)
Graph each inequality-
2x-y=3> 0
2x=5y>10
I just don't understand any of this and I can't find anyone to actually sit here and help me. Please help!!!!

Question 60167: Can someone help me graph this?
Graph 3x + y = 3
Could you show me the graph. I have to send it through the computer, not on paper and I don't have the software to do it.
I sure would appreciate it.
Thank you,
Sher

Question 60168: Can someone help me graph this problem?
Graph 3x + 2y = 6
I don't have the software to graph this. Can someone help me? This is my last week in this class and after this week I will be giving a nice donation to all of the great tutors who have been helping me get through this class.
Thanks so much!

Question 61607: Once again, I've got a solution that doesn't graph properly. My lines do not intersect.
Solve by graphing and give Solution for X and Y:
2X=Y+1
2X-Y=5
Equation 1:
2X=0+1
2X=1
X=1/2 (1/2, 0)
2(0)=Y+1
0=Y+1
-1=Y (0, -1)
Equation 2:
2X-0=5
2X=5
X=5/2 or 2 1/2 (2 1/2,0)
2(0)-Y=5
0-Y=5
-Y=5
Y=-5 (0, -5)
Graphing shows the lines run almost parallel. Did I do this right?

Question 61606: When I solved the problem, my answers come close but am slightly off. Maybe my graph isn't detailed enough.
3X+Y=5
-2X+3Y=4
Equation 1: 3x+0=5 (Solving for X)
3x=5
x=5/3 or 1 2/3 (1 2/3,0)
3x0+Y=5 (Solving for Y)
Y-5 (0,5)
Equation 2: -2x+3(0)=4 (Solving for X)
-2X=4
X=-2 (-2,0)
-2(0)+3Y=4 (Solving for Y)
3Y=4
Y=4/3 or 1 1/3 (0,1 1/3)
Plotting graph intersects appear to be at 1 1/3 and 1 3/4 but doesn't compute when placed in original formulas.
Thanks

Question 61608: Last graph problem today. This time, my lines run on top of each other.
Solve by graphing and give solution for X and Y
3X+2Y=8
6X+4Y=16
Equation 1:
3X+2(0)=8
3X=8
X=8/3 or 2 2/3 (2 2/3, 0)
3(0)+2Y=8
2Y=8
Y=8/2 or 4 (0,4)
Equation 2:
6X+4(0)=16
6X=16
X=16/6 or 8/3 or 2 2/3 (2 2/3,0)
6(0)+4Y=16
4Y=16
Y=4 (0,4)
As I said, the lines run on top of each other so I cannot determine X and Y.

Question 61885: I need someone to show me how to graph this . write the equation of the line with slope-1/2 and -y intercept(0,3) then graph
I worked it out 2y=-x+6 y=3 slope -1/2 I am not sure if that is correct and I do not know how to graph it.
