The graph of the y-axis would be x=0
Take two points from both functions. You
will find out that both slopes are the same.
Also you can see that the functions have different y-intercepts.

I hope this helps
Answer:
Well it would come out to 2x-3y=-9
Step-by-step explanation:
126,945 to the nearest ten thousand is 130,000.
Answer: r = - 20
Step-by-step explanation:
Consider the suggested option:
1) if in 20 gr. of 50% solution given, then pure salt in this mix is 0.5*20=10 gr., and pure water is 0.5*20=10 gr.
2) after Maya added 5 gr. pure salt is 10+5=15 gr. Total mass of mix is 15(pure salt)+10(pure water)=25 gr.
3) new solution is 15/25=0.6 or 60%.
Answer: 25 gr. of 60% salt solution.
