Use technology to plot the graph.
Here it is using wolframalpha.com.
http://www.wolframalpha.com/input/?i=y+%3D+-5;+y+%3D+3x+-+2+for+-2%3C%3Dx%3C%3D2
B.
The solution is where the graphs of the lines intersect. It is at point (-1, -5).
C.
y = -5
y = 3x - 2
-5 = 3x - 2
3x = -3
x = -1
The solution is (-1, -5) which is the same as with the graph.
<em>n = - 1</em>
- <em>Step-by-step explanation:</em>
<em>Hi ! </em>
<em>6 = - 2(10n + 7)</em>
<em>6 = - 20n - 14</em>
<em>20n = - 6 - 14</em>
<em>20n = - 20</em>
<em>n = - 20 : 20</em>
<em>n = - 1</em>
<em />
<em>6 = - 2(10×-1 + 7)</em>
<em>6 = - 2(-10 + 7)</em>
<em>6 = - 2(-3)</em>
<em>6 = 6 (true)</em>
<em>Good luck !</em>
