Answer:
1.5 if you Evaluate and in fraction form 
In 12 years she will be X+12
2 years ago she was X-2
Answer:
y=-x-5
Step-by-step explanation:
Slope is the x, since slope is equal to -1, x=-1. For the y intercept you simply add or subtract the number given to you, since it is -5 you would add a -5 to the end of the equation
