Letters a and b represent a question graph shown below

Hi Andres,

----------------------------------------

Coordinates:

(6,12) and (3,21)

----------------------------------------

Slope:

Formula:

Solution:

Slope: -3

----------------------------------------

Compute the y intercept:

Use: y = mx + b

y = (-3)x + b

12 = (-3) x 6 + b

----------------------------------------

Isolate b:

(-3) x 6 + b = 12

-3 x 6 + b = 12

-18 + b = 12

b = 30

----------------------------------------

Slope Intercept Form:

Follow y = mx + b

m = slope

b = y intercept

y = -3x + 30

----------------------------------------

Point Intercept Form:

Formula: y - y1 = m(x - x1)

m = slope

y1 and x1 = first coordinate set.

m = -3

y1 = 12

x1 = 6

y - 12 = -3(x - 6)

----------------------------------------

Part B:

Approximately for every day he spends delivering he spends a 2.1 minutes on it per day. Well, the reason I say this is because on the chart it says he spends 10 days. When you multiply 10 and 2.1 you get 21!

Hope This Helps :)

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,

hope it
