    Use the slope formula with the two last points \[\frac{ y_{2 } - y_{1}}{ x_{2}-x_{1} }\]

    That will give you the Slope for the last two points

    So the slope would be \[\frac{ -8-7 }{ -2-3} = -15/-5 == \]

    And we know that parallel lines have the same slope

    Did you plug in the slope in y = mx + b form? and plug the first coordinates into that and solve for b?
