Answer:
(-1,2) is domain
Step-by-step explanation:
<span>4x+7x+19=3 x 12 - 4+(5 x 16) - 5 </span><span>
7x+3-2x=4x+2 x 5 + 1

The answer is the first one; it is an arithmetic sequence with a common difference of -40.
First of all, let's find the slope of line L. To find the slope of a line, you write it in the explitic form
, and consider the coefficient
. So, we have

So, the slope of line L is 2/3.
Two lines are parallel if they have the same slope. So, line M has slope 2/3 as well, and we know that it passes through the point (3, -10).
When you are given the slope
and a point
of a line, its equation is given by

So, if you plug your values, you have

which you can simplify into
