True or False: Unit rate, rate of change, and slope are all calculated the same way.
FALSE: although they all mean the same thing, they are found in different ways. Rate of changes needs the equation (mentioned in another problem). Unit Rate is found by finding the amount "per one".

We know that the base cost of a ring with 0 gems is $400. For an additional two gems, it costs $20 extra. Make a graph to represent the x and ys (can include the equation!) At least 3 gems!
x y=10x+400 y
0 y=10(0)+400 400
1 y=10(1)+400 410
2 y=10(2)+400 420
3 y=10(3)+400 430
