Question 476154: I am very lost in this subject and I do need help and plenty of it as I get very flustered to say the least,If someone can help it would be greatly appreciated. With the questions I am about to ask I cam up with (0,5) The question is as follows:
1 Graph equation and identify Y Intercept Y=1/2 x +5
2. Graph by plotting points X=2
3 Graph the equation and plot points Y=1/5x
Answer by josmiceli(19441)   (Show Source):
You can put this solution on YOUR website! Think of the equation as a long series of points
that make up a straight line. The straight line and the
equation are the same thing.
The convention for showing a point is:
(x,y)
You need both an x and a y to be a point, but they
must be points on this line.
You can determine the points this way:
(0,?)
(1,?)
(2,?)
(3,?)
(4,?)
(5,?)
etc.
Or, this way:
(?,0)
(?,1)
(?,2)
(?,3)
(?,4)
(?,5)
etc.
So, given the x or y, you can find the point that
falls on the line.
---------------
The y-intercept occurs where 
 is the y-intercept
The graph is:
----------------------------
This just says: No matter what number I choose for y, I will
alway have . The points on this line will look like:
(2,y), and y can be any number. This is plotted as a vertical line
