area=legnth times width

we notice this is a special case

(a+b)(a-b)=a^2-b^2

area=(a+3b)(a-3b)=a^2-9b^2

Answer:

Option C

Step-by-step explanation:

Find the equation of the graphed line.

Use 2 points, (0, -6) and (2, 4)

m = (4 + 6)/2 = 5
b = -6

The equation is:

y = 5x - 6

Compare with the given line y = 4x + 2

5 > 4 and -6 < 2
