Starting at sunrise, the temperature rose 2.5⁰ every hour. After 8 hours, the temperature was 67⁰. Write an equation in point-slope form to model the temperature, y, after x hours after sunrise. If sunrise was at 6:00 AM, what is the temperature at noon?

•   y+67=2.5(x+8) ; the temperature was 62⁰ at noon

•  y−67=2.5(x−8); the temperature was 62⁰ at noon

•  y−67=2.5(x−8); the temperature was 77⁰ at noon

•  y−8=2.5(x−67); the temperature was 77⁰ at noon
