Answer:
2x+12
Step-by-step explanation:
2x+3(x-2)-3(x-6)
2x+3x-6-3x+18
2x-6+18
2x+12
18% I believe. Because you do the math then you rounded out and then I get 18%
An undefined slope is NOT the same as y= 0, since it is a vertical line. The x-coordinate never changes even if the y-coordinate is different. There is no run.
