F(x) = x + 4
g(x) = 2x - 3
(g - f)(2) = (2x - 3) - (x + 4)
(g - f)(2) = (2x - x) + (-3 - 4)
(g - f)(2) = x - 7

F(x)= x+4
g(x)= 2x-3

(g-x)(x) = [2x-3] -[x+4]
= 2x-x-3-4
= x-7

(g-x)(2)= (2)-7
= -5

What is the equation of the line that passes through the point (-2,0) and has a slope of -2

Tcecarenko [31]

Answer:

y = -2x -4

Step-by-step explanation:

The equation of a line is y = mx + b, where m is the slope of the line, and b is the y-intercept. We are told that the slope of the line is -2, so we can start with

y = mx + b

y = -2x + b

We can figure out the value of b by plugging in the coordinates of the point given (-2, 0)

0 = -2(-2) + b

0 = 4 + b

Subtract 4 from both sides of the equation

-4 = b

Then plug that value of b back into the equation above:

y = -2x + (-4) or y = -2x -4
