So there is two parts to this question?
Answer:

Step-by-step explanation:
Since the line we are trying to study is parallel to the one given by the standard equation 5x + 3y = 6, it needs to have the same slope as this given line has. Let's write then this equation in slope-intercept so we can find what the slope is :

Then the slope of our line must also be "-5/3" in order to be parallel to the given line.
Now, since we also know a point (3, -1) through which the new line should go, we use the point-slope form of a line:

Answer:
C. run 11 units
Step-by-step explanation:
because you run down -6 you rise 11
The sum of interior angles in a regular octagon equals 1080 degrees.
So 1080 / 8 = 135
z = 135
