Question 5) (a) The temperature T at a point on a mountain is a linear function of the height, x, of the point. At the foot of the mountain, the temperature is 25°C. At a height of 100 ft, the temperature is about 23'c.
(i) Find a linear function that relates to x.
(ii) Compute the temperature at a height of 300 ft.
(5) Find r so that the line through (2,6) and (-4,1)
(1) Parallel to 3x + 2y - 7 = 0
(ii) Perpendicular to -x + 3y + 8 = 0
