Answer: 
Step-by-step explanation:
Answer:
You can plot the lines by putting the values of x and y.
For y=x-2, if we put x= 2, then we got y=0
So, the point for this equation will be (2,0). Similarly, you can get many points for the equations and join them to plot lines in the graph.
If we take 771 to be the 100%, and increase it by 98%, thus 100% + 98% = 198.
now, if 771 is the 100%, what is the 198%?
2b=12-18
2b=-6
b=-3
That is the answer
You would have to do 18x2 then 14x2.
