Question

Did i do this correct ?

Answer 1

Problem 3

The graph looks perfect. Nice work.

===========================================================

Problem 4

The line should be completely horizontal and flat. There should be no diagonal slant to the line. Make sure every point on this line has a y coordinate of -2. 

===========================================================

Problem 5

The x value x = 1 does not lead to y = 26. Instead it should lead to y = 29. Other than that, your table looks great.

You made an error with the graph. The x values don't start at 20. Instead you should start at x = 0. You might have mixed up x and y for the graph.
