Answer:
y = - 3x + 6
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Rearrange x - 3y = 5 into this form
Subtract x from both sides
- 3y = - x + 5 ( divide all terms by - 3 )
y =
x -
← in slope- intercept form
with slope m = 
Given a line with slope m then the slope of a line perpendicular to it is
= -
= -
= - 3
Note the line crosses the y- axis at (0, 6) ⇒ c = 6
y = - 3x + 6 ← equation of perpendicular line
First, find the interior angle missing:

Then, we know all the interior angles in a triangle add up to 180º. So, we add all the values for the interior angles and we equate them to 180. We solve the equation normally.

After that, we must add the two angles on a straight line on the right-hand side and equate them to 180.

We compare the equations:

We simultaneously solve by isolating one of the variables (
) in one of the equations (
) and substituting into the other (
):

We substitute it back into the first formula, the one in which we isolated the variable (
):

We now check our answer using the formula we know about the internal angles of a triangle (
):

Now, if
, then we are correct!
So, in conclusion,
and
.
Whatever you multiplied to the denominator, do it to the numerator.
Depending on the first term, the sequences

would work.
If the sequence began at 6,

If the sequence began at 1,

If the sequence began at 3,
