-6x-3y=27 find the x- and y- intercept and graph the equation plotting the intercept -6x+3y=27

First, let's simplify the equation so we have it in the form y=mx + b.

y = -1[x-3]
y = -1x + (-1)(-3)
y = -x +3

We know that m = -1 and b is 3.

The b is the y-intercept, so we can plot the point (0,3).

Next, we start at this point and go down 1 and to the right 1.

We join the dots, and we have graphed the equation.

Good luck.

5x-y=-5 answer x=-1, y= 5 http://www.wolframalpha.com/input/?i=Determine+the+x+and+y+intercept+of+the+graph+for+equation%3A+5x-y%3D-5

-3x+2y=7 answer x = -7/3, y = 7/2 http://www.wolframalpha.com/input/?i=Determine+the+x+and+y+intercept+of+the+graph+for+equation%3A+-3x%2B2y%3D7

Hey! The standard equation of a straight line is y=mx+b (wherein x&y are the coordinates, m is the slope of the line and, b is the y-intercept). Re-arranging your equation to follow the standard equation, you'll have y= -x - 4 or y=(-1)x + (-4).

To plot the equation, try substituting a number to the (x) coordinate to get the value of the (y) coordinate:
Ex:
If x=0, y= -4
If x=1, y= -5
If x=2, y= -6
If x=3, y= -7
Assuming you know how to plot these coordinates, you now have a graph of the equation. Hope I answered your query. Thank you.

Use the definitions of the intercepts.
x-intercepts (or zeros or roots) are the values of the independent variables that make the function equal to zero. To obtain an intercept set y=0 in equation : 5x=-10, mean x=-10/5=-2
y-intercept: value of y when x=0.
Just set x=0 in equaltion and solve for y
-4y=-10, gives y=5/2

And Sorry, I cannot enter the answer in the drop box.

To find the solution, first find the value of y for each equation.
Then substitue one equation into the other so that you only the x variable left.
Then just solve for x.
Once you have a value for x, then you can easily solve for y.


So for the first equation:

3y - 6x = -3
3y = 6x - 3

y = 2x - 1


Now for the second equation:

2y + 8x = 10
2y = -8x + 10

y = -4x + 5

Since both equations equal y, they also equal each other, therefore:

2x - 1 = -4x + 5

Now just solve for x:

2x + 4x = 5 + 1
6x = 6

x=1

Now substitute x=1 into either original equation:

y = 2x - 1
y = 2 (1) - 1
y = 2 - 1

y = 1


Therefore the solution is x=1 and y=1



Good luck, I hope that helps.

This equation can be rewritten by multiplying both sides by 3. Then you will have: y=9-6x The y intercept is (0,9) and the x-intercept is (3/2,0)

You must deactivate the Statistical plots.
Press [STAT].
In list that is displayed delect [4:PlotsOff] and press [ENTER]
Go to [Y=] editor to enter functions or press [GRAPH] if functions already entered.

If the message appears when you try to graph functions deactivate the statistical plots. To do so:

Press [2nd][Y=] to access (STAT PLOTs)
Select [4:PlotsOff] then [ENTER]

That should solve your problem. Post a comment to this thread if you still have trouble graphing.

If the message appears in another context, it sure would help knowing the context of the error.

This is probably because you have the stat plot on. You would need to go to y= and then go to the top where it says stat plot 1 and un highlight it if it is highligted. That should fix your problem.

If either error occurs when trying to graph a function (not a STAT PLOT), the error can be corrected by turning off the STAT PLOTS. The following steps will turn the STAT PLOTS off, allowing the graph of the function to be displayed.• Press [2nd] [Y=] to access the STAT PLOTS menu.
• Select 4: PlotsOff.
• Press [ENTER].
• Try graphing a function like y = x^4-3x^3+6x-1
