Question

What did I do wrong and how do I fix it

Answer 1

From the question, the equation of the line is given as

`\begin{gathered} y=-3x-8 \\ comparing\text{ this to the equation of line in slope-intercept form, we have } \\ y=mx+b,\text{ where m is slope and b is y-intercept} \end{gathered}`

So this means that the slope of this line m is -3.

A line that is parallel to this line will also have a slope of -3

So, looking at the 3rd option

`\begin{gathered} y=-3x+7 \\ it\text{ has a slope of -3} \end{gathered}`

Hence the answer is

y = -3x + 7, the 3rd option
