How to Graph a Line?
Method 1:
First you create a plane then you graph on it all the points there's an x-axis a horizontal line and an x-axis a vertical line and 0 which is the origin of the plane and while graphing a line you always start from 0 the origin then you go right for the positive side or left for the negative side on the x-axis if it says positive 6 then go 6 spaces to the right then I move up or down it depends on what it wants for the y-axis negative or positive if negative go down if positive go up so if it says positive 7 then go up 7 you should be at a point were you went 6 spaces to the right then 7 spaces up.

here the point A is in quadrant I of the plane which is positive x and y-axis points B and C are in quadrant II which has a negative x-axis and positive y-axis point D is in quadrant III which has both y and x-axis negative last but not least point E and F which are in quadrant IV in which the x-axis is positive and the y-axis is negative.

Method 3:
First, you graph a plane then you plot the y-intercept also known as b then the slope known as m in an equation called y=mx+b then you use a method called rise and run if the y-intercept is negative you go down if it's positive you go up then you move right if positive, left if negative.
-
in a relation there is a domain all of the x-coordinates and Range all of the y-coordinates so you find the Range and domain of each point then you write them all down in a chart and see if there's any repeated numbers if there's 2 of the same number but one on each side its okay they both have to be in the same side for it to not be a function but if all numbers are different then its a function.

How to use y=mx+b?
There is only 1 method:
m is the slope and b is the y-intercept to find the rise and run use m and also use m to know which direction to go. The point of intersection has x as 0 as it falls on the y-axis this means you can find a point on the line (0,b).
