Answer 1

i am lost

Answer 2

Hmmm....

Lets first round off the points... Now we see that the x-intercept which is x in (x,y) is rounded to a whole number... but the y-axis isnt and has a decimal to it....

so we need to round 49.99, 99.98, 149.97, and 199.96.... so what would these numbers round too?

Answer 3

round what place??

Answer 4

We would round these numbers to where it doesnt have a decimal.... so 49.99 would round to 50....

Answer 5

50,100,150 and 200

Answer 6

I agree with 563blackghost in that I'd choose to round off the four y vales and mark the y-axis accordingly, exactly as pooja95 has just done.

Answer 7

Trying to mark the y-axis with mixed fractions such as 49.99 would be a waste of time.

Answer 8

@563blackghost what should I do next?

Answer 9

Correct! Now we need to label the y-axis... So we would start with 0 now what would the highest y-value be....we need to make sure that it can include all points...

Answer 10

200?

Answer 11

Correct! So the y-axis would be labeled from 0 to 200 ^^

Answer 12

so that's the answer?

Answer 13

Yup

Answer 14

From 0 to 200 at intervals of 50 that is the only option that says 0 to 200

Answer 15

Yup... if we double check if it is at intervals of 50 we would look at the rounded points....

50, 100, 150, and 200 now do they go by 50's?

Answer 16

yes thanks you will get a medal and fan!
