Answer:

Option D that is y=-2(x+1) is the correct choice.

Explanation:

Given equation:

y=2x-2

We have to find another equation which has only one solution.

Standard form of equation:

1.a_1x+b_1y+c_1=0

2.a_2x+b_2y+c_2=0

Condition for one solution.

\frac{a_1}{a_2} \neq \frac{b_1}{b_2}

We have to arrange other equation in the form of  ax+by+c=0

Mark all the options as a,b,c and d.

a.\ 2x+1-y=0

b.\ 2x-2-y=0

c.\ 2x-4-y=0

d.-2x-2-y=0

Now from the above options we can see that option a,b\ and\ c are not providing the desired result.

So

\frac{a_1}{a_2} \neq \frac{b_1}{b_2} can be obtained from the last option.

As

\frac{a_1}{a_2} \neq \frac{b_1}{b_2} ,\frac{2}{-2} \neq \frac{-1}{-1} ,-1\neq 1

Option D that is y=-2(x+1) is the equation from where we can obtained only one solution.
