Rational ! the number doesn't repeat forever or anything like that. it simplifies nicely.
Answer:
The slope of line is 2/3.
Step-by-step explanation:
To calculate slope you do :
y2 - y1 / x2 - x1
Her work is incorrect because she accidentally changed -14 to -7 in the second step.
Working it out from the top we get
(x-14)+11=x-(x-4)
x-14+11=x-x+4
x-3=0+4
Final answer:
x=7
