Probability = no of outcomes / total outcomes First draw = no of blue mables / total mables = 3 / (4 + 3 + 3) = 3/10 For the second draw, since there was no replacement of the first draw, the blue mables has reduced by one, and the total mables has reduced by one. Second draw = no of remaining blue mables / total remaining mables = 2/9
when a line is parallel to another line that means the slip of the lines are going to be the same and since the y-intercept of the other line was given to you, you would just put them together in one equation.
