PLEASE HELP VERY FAST! (06.02)Eric plotted the graph below to show the relationship between the temperature of his city and the number of cups of lemonade he sold daily:

A scatter plot is shown with the title Lemonade Sales. The x-axis is labeled High Temperature, and the y-axis is labeled Cups of Lemonade Sold. Data points are located at 30 and 4, 40 and 6, 40 and 8, 50 and 2, 55 and 10, 65 and 14, 70 and 16, 75 and 14, 85 and 19, 90 and 20.

Part A: Describe the relationship between the temperature of the city and the number of cups of lemonade 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)

Part A: :

The relationship that is being shown in this problem is: As the temperature increases, then the number of lemonade cups also increases. 

Part B:

The line of bets fit would be at the starting point of: (15,0) and the end point on the graph would be (90,20)

To find the approximate slope I would use the equation: (Y2-Y1)/(X2-X1) which I would get 20-0 which in conclusion ends up giving me 90-15. Now I end up having to do 20/75 which is equal to .266 so in conclusion:

Slope= .266 and the y-intercept= (15,0)

Pls: Mark Brain-lest (I don't know how to spell it)  

Thank You :))

Part A:

The relationship between the temperature of the city and the number of cups of lemonade sold is the higher the temperature, the more lemonade is sold.

Part B:

The line of best fit would start at (15,0) and end at (90,20)

Slope= 0.266

y-intercept= 15,0

(mark the person above me brainliest)

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
