Please help me with this problem......
kupik [55]

The red graph is the result of a vertical translation, 4 units down, of the black graph.

This means that, whenever the black graph associates

x\mapsto f(x)

The red graph must associate 4 less to the same input:

x\mapsto f(x)-4

So, the equation for the red graph is

y=f(x)-4

or, equivalently,

y+4=f(x)

which set of steps shows the solution to the equation 2y = −8? y = −8 − 2; y = 6 y = −8 ÷ (−2); y = 4 y = −8 ÷ 2; y = −4 y = −8
xz_007 [3.2K]

Answer:  The correct option is

(C) y = −8 ÷ 2; y = −4.

Step-by-step explanation:  We are given to select the correct steps that shows the solution to the following equation :

2y=-8~~~~~~~~~~~~~~~~~~~~~~~~~~(i)

We know that

the solution to the equation ax=b,~~\textup{a,b are real numbers} is given by

ax=b\\\\\Rightarrow x=b\div a.

Therefore, the solution of equation (i) is as follows :

2y=-8\\\\\Rightarrow y=-8\div 2\\\\\Rightarrow y=\dfrac{-8}{2}\\\\\Rightarrow y=-4.

Thus, (C) is the correct option.
