A small greenhouse's temperature increases linearly over four days. At day 2 the temperature was 14°C and at day 6 it was 26°C. (i) Compute the slope (rate of temperature change per day). (ii) Write the temperature in point-slope form using the day-2 data, and (iii) convert to slope-intercept form.

• A. (i) 3(ii) y + 14 = 3(x + 2)(iii) y = 3x − 8
• B. (i) 1.5(ii) y − 14 = 1.5(x − 2)(iii) y = 1.5x + 11
• C. (i) 3(ii) y − 14 = 3(x − 2)(iii) y = 3x + 8
• D. (i) 2(ii) y − 14 = 2(x − 2)(iii) y = 2x + 10
