Assuming, you are to create your own table of values, I suggest you
1. Solve the equation for y
2. Choose numbers for x (x=0 and x=1 are easiest since you only need two points to graph a line).
3. Plug the numbers in the equation for y in place of x. The solution is a y value
4. Create a table with the columns labeled x and y
5. Write your chosen x values in the column labeled x
6. Write the y values you computed in Step 3 in the y column
7. This is the table of values! Graph the x and y pairs on paper. Draw a line thru the dots. Make sure the line does not just connect the dots but extends past the dots.

Praise GOD!! You are finished!!

in order to graph the equation you first get the y all by itself on one side of the equals sign. so, it would be y=4x-1 because you can add 4x to both sides. Then, you plug in multiple values for x and find out what the y value would be when x is equal to that. This gives you a point on the graph. For example, if you plug in 1 for x the equation would be y=4(1)-1 which is equal to y=4-1 so y=3 The point, then, would be (1, 3) because you put the x value first. Make a table where the left side of the column is the x value and the right side of the table is the y value when the x equals what is on the left side. Sorry if this was a little confusing, but i hope it helps.

An easy approach would be to rewrite the equation in an equivalent form as: y = 4x-1. Now you can make a table of values by assigning the x (independent value) values, substituting them in, and then simplifying to solve for the corresponding value of y (dependent value). Consider this as a start:
See the supporting work (substituting the values of x in to solve for the corresponding value of y) below the table of values.


x | y
---------
-2 | -9
0 | -1
1 | 3

If x = -2, then y = 4(-2)-1 = -8-1 = -9 Plot the point (-2, -9)
If x = 0, then y = 4(0)-1 = 0-1 = -1 Plot the point (0, -1)
If x = 1, then y = 4(1)-1 = 4-1= 3 Plot the point (1, 3)

Now plot the points on a piece of graph paper and use a straight-edge (ruler) to sketch the line that passes through all of the points. Give it a try. :-)

You need to isolate "y". So: y - 4x = -1 becomes y = 4x - 1.

Now that your equation is in the right format, plug in values for "x". Use -3, -2, -1, 0, 1, 2, 3, but start at higher numbers if needed. Example: -5, -4, -3, -2, -1, 0 etc...

Creating a table of values is an easy thing to do. Make a table, something similar to:

X | Y
--------------
-3 | -13
--------------
- 2 | -9
--------------

... and so on...

The Y value is the number you obtain from plugging in -3 into y = 4x - 1.

Ok...

To create a table, just pick values for x or y and solve for the other variable, such as:

x = 1, y - 4(1) = -1, y - 4 = -1, y = 3
(1, 3)

x = 2, y - 4(2) = -1, y - 8 = -1, y = 7
(2, 7)

x = 0, y - 4(0) = -1, y - 0 = -2, y = -1
(0, -1)

There are 3 points :) If you need more, plug in other values for x!

Best of luck, my friend!

First...... x needs to go before y.
4x-y= -1
make a table by drawing a horizontal line and two vertical lines down the middle of that line. x is on the left side of the table the equation is in the middle and y is on the right. insert: -1, 0, 1, and 2 for x. insert x in the equation and solve for y.

4(-1) -y= -1
-4-y= -1
+4 +4
(-1) -y= 3(-1)
y= -3
then graph as (4,-3),.......

is this what you wanted?

This sort of question cannot easily be answered on here.

Pick several x values. Plug the x's in the equation and solve for y. Write the y values next to the corresponding x value. Graph the points. Draw a line through the points you have graphed.

y-4x=-1 0r,y=1+4x, Hence for the values of x=0,1,and 2 the respective values of y will be 1,5 and 9. So take the points (0,1),(1,5) and (2,9)

y=4x-1
when x=-2 y=-9
when x=-1 y=-5
when x=0 y=-1
when x=1 y=3
when x=2 y=7
the ordered pairs are
(-2,-9);(-1,-5);(0,-1);
(1,3);(2,7)

First y = 4X-1
-----------------
x ||||||||||||||||||||||| y
-----------------
-10 |||||||||||||||| -41

-3 |||||||||||||||||| -13

-2 |||||||||||||||||||||| -9

-1 |||||||||||||||||||||| -5

0 |||||||||||||||||||||| -1

1 |||||||||||||||||||||||| 3

2 |||||||||||||||||||||| 7

3 ||||||||||||||||||||||| 11

10 |||||||||||||||||||||| 39
_______________________

Put your points at (-10,-41) ||| (-3,-13) ||| (-2, -9) ||| (-1,-5) ||| (0, -1) ||| (1,3) ||| (2,7) ||| (3,11) ||| (10,39)

This should be good enough to draw a graph. Good Luck!
