Answer:
1) 
2) 
3) 
Step-by-step explanation:
<em><u>Question 1:</u></em>
All you have to do is solve for y to get the slope intercept form.

So the equation is 
<em><u>Question 2:</u></em>
Now for this one you have to find the line perpendicular to the previous equation.
<em> Finding the slope:</em>
So first we need to find the slope and usually the slope of a perpendicular line is the opposite and the reciprocal to the original equation. So instead of
it will be
or even easier to manage
.
<em> Finding the y-intercept:</em>
For the y-intercept we need to plug in what we know into this formula....
We know the slope is
and we could use the ordered pair that they provided us with
. The -6 is the x and the -19 will be the y. Now let's plug in and solve.

<em> Writing the equation:</em>
Now we know all the information needed to write the equation.

Now we just fill it in the formula...

<em><u>Question 3:</u></em>
For a parallel equation the slope will be the same in order for them to be parallel to each other.
<em> Finding the y-intercept:</em>
For the y-intercept we need to plug in what we know into this formula....
We know the slope is
and we could use the ordered pair that they provided us with
. The -8 is the x and the 6 will be the y. Now let's plug in and solve.

<em> Writing the equation:</em>
Now we know all the information needed to write the equation.

Now we just fill it in the formula...
