2-(3x-4)=-15 is this true or false

The number if marbles of different colors stored in a hat is listed below: 4 red marbles 10 green marbles 7 blue marbles. without looking in the hat, dan takes out a marble at random. he replaces the marble and then takes out another marble from the hat. what is the probability that dan takes out a blue marble in both draws?

Give me the equations of two lines that have the same slope but are not parallel.

I'm confused on this could anyone me and show me what i need to do to solve it.
