graph y=x+6 in coordinate plane

The coordinate plane is simply a set of two graph axes, the x axis and y axis, which cross each other at a right angle. In order to graph a function, such as y = x + 6, you need to use the x coordinates to find the y coordinates. So if x = 1, y = 1 + 6, which means y = 7. Looking at the graph, you can map out several points in y = x + 6 by picking several x values and plugging them into the function. When you do this, you will get a set of points, such as (1, 7), (2, 8), (3, 9), etc. Next you plot these points on the graph, meaning you find the vertical line that runs through the x axis at the first number in each pair and the horizontal line that runs through the y axis at the second number in each pair. Where those lines cross is where you put your point. Finally, when you're done plotting the points, you can simply connect them to get your function graph of y = x + 6. Remember that the function extends past the points you plotted, so make sure you put arrows on the ends. I hope this helps!
