Learn how to be better at ALGEBRA :P
Algebra is easy!
All you have to do is find the value of the variable (ex. a or b)
Move the five over to the other side.
When a negative number switches side, it becomes a positive.
Rearrange the following
if there is a question like:
Don' go like ' ohno there are two variables! Im DOOOOOOMMMMMEEED!'
first, your objective is to make y the subject:
y=13-x (X is brought to the other side, so it becomes a negative)
Your equation is 'y=13-x'
Now you can plot your graph:
If a positive number switches side, it becomes a negative.
