In 1998 the u. s. hispanic high school dropout rate was 29.5% and in 2008 it had dropped to 18.3%. a) let d (the outputs) represent the u. s. hispanic high school dropout rate and y (the inputs) represent the years since 1990. find a linear model for the dropout rate given the year. (round to two decimal places.) d= b) what is the vertical intercept of your model? (write your answer as a comma separated ordered pair.) the vertical intercept is when the graph crosses the output axis. (y, d)= c) the vertical intercept of this model tells me that in the year the hispanic dropout rate will be percent. data obtained from
