Can 3 meters and 2 km be expresses as a ratio.

yes, you can just write it as 3m : 2km

Step-by-step explanation:

I don't know if this is completely right, but I know you can also turn 3m into km by multiplying it by 1000, (because there are 1000 m in every km) and then solve because 3000km/2km = 1500km

So to solve would be 1500 km. I hope the first answer is right though. Did I help? Let me know in the comments

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.
