Mark and jessica are each making a linear model to predict the population of squirrels in the town park. the are both using the same data points to find an equation of the line of best fit: the squirrel population, p, in 2002 and the squirrel population, q, in 2011. mark is using the year as the x-value, and he represents his data as (2002, p) and (2011, q). jessica is using the years since 2000 as her x-value, and she represents her data as (2, p) and (11, q).

which statement best describes how their prediction equations compare?

a. their equations have the same x-coefficients and y-intercepts.
b. their equations have different x-coefficients and y-intercepts.
c. their equations have different y-intercepts but the same x-coefficients.
d. their equations have the same y-intercepts but different x-coefficients.
