Answer:
<h2>B. 2x + y = 4</h2>Step-by-step explanation:
Having the system of equations in its simplest form
If
then the system of equations has infinitely many solutions.
If
then the system of equations has no solution.
If
then the system of equations has one solution.
We have the equation
Convert to the standard form Ax + By = C<em>:</em>
<em /><em> add 2x to both sides</em>
The slope (or average rate of change) formula is: 
. It is easy to remember as "slope is easy and fun, rise over run" where the y-values of the 2 points would be the "rise" and the x-values of the 2 points would be the "run" So with two points, you label one point as 
and the other as 
. Then you insert these points into the slope formula (m represents slope). So, 
where (-3,6) is x2 and y2 and (5,1) is x1 and y1. It would simplify to 
.
