The slope of this line is the difference of the y values divided by the difference of the x values. Solving this give 4/-3. Then, you already know the b in y = mx+b, which is 2, because you already have the value (0, 2). So, the answer is y = $-\frac{4}{3}$ x + 2

$y=mx+b\medskip\\\begin{cases}-2=3m+b\\2=b\end{cases}\Leftrightarrow\begin{cases}-2=3m+2\\b=2\end{cases}\Leftrightarrow\begin{cases}m=-\dfrac{4}{3}\\b=2\end{cases}\medskip\\y=-\dfrac{4}{3}x+2$

Answer:

A.)lPace the compass needle on M and, keeping the compass width the same, draw two arcs that intersect

Step-by-step explanation:

In the construction of a line perpendicular to AB←→ and passing through an external point M the first step must be"Place the compass needle on M and, keeping the compass width the same, draw two arcs that intersect AB←→". After that you can draw arcs from intersection points (keeping the compass width same as before) to the opposite side of M, name it as N than use straightedge to draw line passes through M and n that would be perpendicular line to AB.
