The price of attending college is increasing. Using data from 2000-01 academic year through 2010-11 academic year, the cost of attending a two-year college could be modeled with a linear equation of the form y = 170.19x + 6224 where x is in years after 2000-01. Which of the following is a correct interpretation of the slope and y-intercept? Mark all that apply. The cost to attend a 2-year college was around $170 in 2000-01. The y-intercept is meaningless. The costs increased by about $170 per year since 2000-01 (on average). The cost to attend a 2-year college was around $6224 in 2000-01. The costs increased by about $6224 per year since 2000-01 (on average)
