Answer:
<em>-</em><em>7</em>
Step-by-step explanation:
<em>a=9 a2=2 a3=-5 a4=-12 </em>
<em>d = a4-a3 ,a3-a2, a2-a.</em>
<em>so</em><em>: </em>
<em>d = -12-(-5) =-12+5 =-7</em>
<em>also;</em>
<em>d = -5-2 = -7</em>
<em>and </em>
<em>d</em><em>= 2-9 =-7</em>
<em> so the common difference is -7</em>

Step-by-step explanation:
Answer:
(0,3), graph is attached.
Step-by-step explanation:
We know that the first equation will increase 2 points in y for every 1 x, since the constant next to x is 2. We also know it's y-intercept will be 3.
As for the second equation, we know it will have no y and instead run through the y=3 line, crossing every value of x.
Graphing this, we see that these lines intersect at (0,3) so that's the solution to this system.
Hope this helped!
