50 point

part a: in your own words, describe the relationship between the temperature of the city and the number of cups of hot chocolate sold. (2 points)
part b: describe how you can make the line of best fit. write the approximate slope and y-intercept of the line of best fit. show your work, including the points that you use to calculate the slope and y-intercept. (3 points)

The equation for a line of best fit could be: y = -3.5x + 105

Part A: Looking at the data, the points tend to fall from left to right. This means as the temperature goes up, the amount of hot chocolate decreases.

Part B: To draw a line of best fit, you could use the points (10, 70) and (20, 35). They fall in the middle of the data. 

The slope between them in -3.5. (35 - 70) / (20 - 10). Using that and one of the points, you can find the y-intercept to be 105.

Putting the slope and y-intercept together, we can write the equation: 

y = -3.5x + 105

Hope this helps!

PART A: 2 hot chocolates being sold means the temperature is 40 degrees, etc.

PART B: I make the line best fit by eyeing the line between many points,.

To determine the slope we should use the formula; y2 - y1/x2 - x1

Lets fill it in, but first we must find the coordinates of the line which is; (60, 14) and (80, 10)

10 - 14 / 80 - 60 = 4 / 20 = 5

the slope is 5

i would need to see the dot plot : )
