: One of the major problems I am having with algebra, Geometry,ect. Is that I am having difficulty understanding how to graph. The problem I am having trouble with is:
Graph the line x+y=5, it also says something about filling in the input/output table. Though I am having more difficulty about graphing the equation. Please help me. Thank You=) This question is from textbook algebra

Graphing can be a pain.
The equation you've been given is a line. (both x and y have an exponent of 1).
To graph a line, all you need is two points. Usually, it is easy to find the points where x = 0 and y = 0. So let's find those two.
x =0 --> -->
so one point is (0,5)
Now set y = 0. --> -->
Another point is (5,0)
Now plot those two points and draw the line that goes through them.
When you are asked to created a 'table', you are being asked to setup something like
x y
------
0 | 5
1 | 4
-1| 6
etc etc. Again, since you know you have a line, 2 points will be all you need to be able to graph it. Just remember, the table, the graph and the equation are just different ways to represent the 'same thing'.
