Which equation does the graph below represent?

a coordinate grid is shown. the x-axis values are from negative 5 to positive 5 in increments of 1 for each grid line, and the y-axis values are from negative 15 to positive 15 in increments of 3 for each grid line. a line is shown passing through the ordered pairs negative 4, 12 and 0, 0 and 4, negative 12.

y = fraction negative 1 over 3x
y = −3x
y = 3x
y = fraction 1 over 3x

Step-by-step explanation:

The equation of a line passing through two points (a,b) and (c,d) is given by :-

In the given graph , the line is passing through (0,0) and (-4,12).

Then, equation of the line will be :-

Hence, the equation represented by the given graph :

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
