how to graph y=x+3
you make a table of values and then you graph the line. The line could be either straight or curved.
like jannie said..
so your table would look something like
_y____x_
-2 -5
-1 -4
0 -3
1 -2
2 -1
3 0
4 1
you can basically choose any number you want x to be then find y
oops the right numbers are suppose to be under the x
To graph the equation y = x + 3, you can follow these steps:
1. Choose a range for the x-values: Decide on a suitable range for the x-values you want to plot. For instance, you can select x-values from -5 to 5.
2. Create a table of values: Pick a few x-values within your chosen range and calculate their corresponding y-values using the equation y = x + 3. For example, if you choose x = -3, -1, 0, 1, and 3, their respective y-values would be 0, 2, 3, 4, and 6.
3. Plot the points: On a coordinate plane, locate the points from the table you created in step 2. For instance, when x = -3, y = 0, so plot the point (-3, 0). Repeat this for the other points.
4. Draw a line: Once you have plotted the points, draw a straight line that connects them. The line should extend beyond the points on both ends to represent the full graph.
In the case of the equation y = x + 3, the graph will be a straight line with a slope of 1 (which means for every 1 unit change in x, y will change by 1) and a y-intercept of 3 (where the line crosses the y-axis).
Please note that this is a basic explanation of how to graph the equation. For more complex functions, different approaches may be required.
