What do the letters in FOIL stand for? Explain how you would use foil to multiply the following binomials: (2x + 3)(x - 6)
FOIL stands for First, Outside, Inside, and Last. To multiply (2x + 3)(x - 6): First: 2x * x = 2x^2 Outside: 2x * (-6) = -12x Inside: x * 3 = 3x Last: 3 * (-6) = -18; Combine all like terms: -12x + 3x = -9x (2x + 3)(x - 6) = 2x^2 - 9x - 18

FOIL stands for First, Outside, Inside, and Last.
To multiply (2x + 3)(x - 6):

First: 2x * x = 2x^2
Outside: 2x * (-6) = -12x
Inside: x * 3 = 3x
Last: 3 * (-6) = -18;

Combine all like terms:
-12x + 3x = -9x

(2x + 3)(x - 6) = 2x^2 - 9x - 18

where b is the constant. (-1, 0) m = -2

y = mx + b
0 = (-2)(–1) + b
0 = 2 + b
-b = 2
b = -2

the equation of the line is
y = -2x - 2
