*****MAY 2015 INTERNATIONAL SAT*****

i just wanna know why people say its x-18 not x-16!!

i pluged in like 5 points and the answer was x-18 !

If it has a slope of 1 then that means that y=x, but because x started at 16, therefore y=x-16. I’m not sure but that’s how I did it

@amregysat i know but the line that best fits the points is x-16 not x-18 if u look at the line itself not the points

I’m pretty sure you can’t just plug in random points because they give you the line of best fit

and also the question is about the line that best fits the point not the points itself right??

@willinson what do u mean?

@Kombeler @Willinson do you know the answer for number 15 on the math section on the 16 questions section. it said something like "every year a number increases by 10% which of the following would express unit’s A currency " also what is the answer to number 27 on the ID errors, the one before the lions mane ?

@amregysat its was 2(1.1)^t

yes it was 2(1.1)^t

but what about x-18 or x-16???

was it C or E @Hannah69 ?

@amregysat I don’t remember the exact chouce, I just remember the answer. And as for 27. I put A.
Ambassador of a country.
Ambassador to a league or court of a country /team
I read that once I am not sure

@Kombeler sorry man I kinda forgot how the graph looked like but I assume that if the slope is 1 then y will equal to x. If you choose x=17, for example, because x starts at 16, then y=17-16=1. But if the answer were to be x-18, then y=17-18=-1, which doesn’t make sense. I hope u understand what I’m talking about I’m not really good at explaining

@Willinson do you remember that flower q? If you do what was your answer?

@willinson ohhh thats another way to put it :smiley:

@willinson thats a good point to put it… i didnt think to put 17 or even 16 to get the y amazingly done but still manyt people say its x-18! XD
Whats ur score in math?
@hannah69 what flower? the smooth and wrinkled one?

@Kombeler this is my first attempt officially on the sat but I usually score over 700 on math during practice if that helps

@willinson nice good luck though
if u get the correct answer for the question please pm me

@Kombeler yes!
