You are supposed to find the coordinates of the vertex of the graph. An example that I know would be y = |x| + 3. The answer would be 0,3.
Please help me with this...I'm not really sure what to do.
y = |x+8|

Not sure how far in math you are, so here's the College Algebra/Pre-Calc version of finding your vertex:

The "parent function" for absolute value is y = IxI
The vertex is always at (0,0)

With transformations, we know that manipulating a variable inside parentheses (in this case inside the absolute value symbols) shifts the graph either left or right. Positive numbers move left, negative numbers move right. Since the equation is x+8, your vertex moves 8 points to the left along the x-axis. Your x-value is now -8, the y-value stays the same.

Vertex @ (-8,0)

y = x/8 so
8y = x so on the graph have y as vertical an x as horizontal and your line will start at 8 squares up and 1 in, then 16 up and 2 in and so on. You will have a steep line rising at a sharp angle.
