Make a little dot on the y-axis at the point y=3. Draw a line through that point that slopes down to the right, dropping down 4 units for each unit it progresses to the right, or rising 4 units for each unit it progresses to the left.
It will be a right angled triangle with sides of 3 and 4 units with an hypotenuse of 5 units in length.

Can someone please help me???
In cartesian coordinates (x, y) = (3, -4)
(2,1)
The vector sum of (7 units down) + (3 units up) is (4 units down).
The graph of is shifted 3 units down and 2 units right. Which equation represents the new graph?
For this translation, you need to replace every occurence of "x" with "x-3", and every occurence of "y" with "y+5".

if a figure is shifted 3 units to the right, you add to the coordinate

A number line can help you visualize this. See http://en.wikipedia.org/wiki/Number_line for an example, and a description. On a number line, adding 3 means to go 3 units to the right; if you start at -9 and go 3 units to the right, you end at -6, 'tis as simple as that. (Subtracing a number means going a certain number of units to the left.)
It means that for every three units of distance that you move to the right you move one unit up (equivalently, 3 left and 1 down).
