1. True
2. False. Simple interest is computed only once a year. Compound interest is
computed more often, like semi-annual, quartly, monthly etc. Interest is earned

1. False
Slope = 0
Equations are in the form of y = constant
Example y =2
2. False
If P is (1,1) then Q will have to be (-2,5) which means Q is not 2 units to the right
of P
