Math
to get y values you have to put the x values into the y equation. Y is a function of x. So for x=1,y=2.05. x=2, y=4.05. x=3, y=6.05. x=4,y=8.05. x=5,y=10.05. x=6,y=12.05. Does that clear things up?
April 30, 2015

Math
no, you have to plug in the values for x to get values for y. For instance, if you want x is 2, then y would have to be y=2(2)+.05 which is 4.05. If you want x as 1, y=2.05. Does that make sense Island G?
