Need help and fast this work is due soon

Will give brainliest summations with algebraic expressions image shown

Which expression can be used to determine the slope of the line that passes through the points -6, three and one, -9

Which is an accurate comparison of the two data sets? the commute to work is typically shorter and more consistent than the commute home. the commute to work is typically shorter but less consistent than the commute home. the commute to work is typically longer and less consistent than the commute home. the commute to work is typically longer but more consistent than the commute home.
