Answer:

The answer is below

Step-by-step explanation:

The equation of a straight line is given as:

y = mx + b; where m is the slope of the line and b is the y intercept (that is value of y at x = 0).

a) From the graph, we can see that the straight line touches the y axis at $100 in which the temperature is 0 degrees. Therefore the y intercept is:

(0, 100)

b) The slope of the line can be gotten by taking two points that the line passes through. Using the points (0, 100) and (12, 500):

slope(m)=\frac{y_2-y_1}{x_2-x_1} =\frac{500-100}{12-0} =33.3
