Please show me step by step how to Make a table of solutions for the equation,and then use the table to graph the equation.

I thought I answered this for you on Sunday

Sorry Mr. Reiny I could not find the page where I had asked the question on Sunday when I went back to look, thanks for the link and the answer.
To make a table of solutions for the equation y = 2x - 1 and then use the table to graph the equation, you need to follow these steps:
Step 1: Choose a range of x-values.
Decide on a set of x-values that will help you plot points for the table. Let's choose a range from -3 to 3.
Step 2: Substitute each x-value into the equation to find the corresponding y-values.
For each chosen x-value, substitute it into the equation y = 2x - 1 to calculate the corresponding y-value. Let's calculate the values:
When x = -3: y = 2(-3) - 1 = -7
When x = -2: y = 2(-2) - 1 = -5
When x = -1: y = 2(-1) - 1 = -3
When x = 0: y = 2(0) - 1 = -1
When x = 1: y = 2(1) - 1 = 1
When x = 2: y = 2(2) - 1 = 3
When x = 3: y = 2(3) - 1 = 5
Step 3: Create a table to organize the x and y values you calculated.
List the x-values in one column and their corresponding y-values in another column. Your table should look like this:
x | y
--------
-3 | -7
-2 | -5
-1 | -3
0 | -1
1 | 1
2 | 3
3 | 5
Step 4: Plot the points on a graph.
Use the table you created to plot the points on a graph. On the x-axis, locate the values -3, -2, -1, 0, 1, 2, and 3. On the y-axis, locate the corresponding values -7, -5, -3, -1, 1, 3, and 5. Plot the points (x, y) for each pair of coordinates.
Step 5: Connect the points to form a straight line.
Once you plot all the points, connect them using a straight line. This line represents the graph of the equation y = 2x - 1.
That's it! You have now created a table of solutions for the equation y = 2x - 1 and used it to graph the equation.
