This is a ratio problem

4/7/1 gal = x/10.5 gal

4/7 x 10.5 = 6

1x = 6

so x is 6

The table shows revenue R (in millions of dollars) of a company when it spends A (in millions of dollars) in advertising.

Orlov [11]

Advertising is x and revenue is y

(0,2)(2,6)
slope = (6 - 2) / (2 - 0) = 4/2 = 2

y = mx + b
slope(m) = 2
(0,2)...x = 0 and y = 2
now we sub and find b, the y int
2 = 2(0) + b
2 = b

so ur equation is : y = 2x + 2

spends 10 mill on advertising.....so x = 10
y = 2x + 2
y = 2(10) + 2
y = 20 + 2
y = 22.....so the revenue (y) of the company is 22 (million)

Point (0, 0)

Point (1, -2)

<u>Step 2: Find slope </u><em><u>m</u></em>

Substitute: $m=\frac{-2-0}{1-0}$
Subtract: $m=\frac{-2}{1}$
Divide: $m=-2$
