(3,-1)(4,3)
slope(m) = (3 - (-1) / (4 - 3) = 4/1 = 4

y = mx + b
slope(m) = 4
use either of ur sets of points....(4,3)...x = 4 and y = 3
now sub and find b, the y int
3 = 4(4) + b
3 = 16 + b
3 - 16 = b
-13 = b

so ur equation is : y= 4x - 13 <==

Question:

Solution:

Consider the following two functions:

$f(x)=2x+8$

and

$g(x)=x^2+2x-8$

Now, consider the following definition:

$(f-g)(x)=f(x)-g(x)$

thus, we get:

$\begin{gathered} (f-g)(x)=f(x)-g(x) \\ =\text{ (2x+8)-(}x^2+2x-8\text{)} \end{gathered}$

this is equivalent to:

$=\text{ 2x+8-}x^2-2x+8$

this is equivalent to:

$=-x^2+16$

So that, we can conclude that the correct answer is:

$(f-g)(x)=-x^2+16$
