Answer:
1)

2)

3)

Explanation:
Question 1:
All you have to do is solve for y to get the slope intercept form.

So the equation is

Question 2:
Now for this one you have to find the line perpendicular to the previous equation.
Finding the slope:
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
.
Finding the y-intercept:
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.

Writing the equation:
Now we know all the information needed to write the equation.

Now we just fill it in the formula...

Question 3:
For a parallel equation the slope will be the same in order for them to be parallel to each other.
Finding the y-intercept:
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.

Writing the equation:
Now we know all the information needed to write the equation.

Now we just fill it in the formula...
