Fan and Medal will be given ! In order to build a scale model of the trail, the drawing is enlarged on the coordinate plane. If two corners of the trail are at point A(−2, 7) and point D(−10, −1), what is another point that could represent a corner of the trail?

i guessed tho , I want to know how to get it @sdfgsdfgs

Can you help me ?

OK all 4 choices have 7 as the y-coordinate. so no need to worry about that right?
Aizhalee
  • Aizhalee
Yes .
sdfgsdfgs
  • sdfgsdfgs
look at A and D, what is the difference between their y-coordinates? then look at G and H, what is the difference there?
Aizhalee
  • Aizhalee
A y coordinate is 7 and D ycoordinate is -1 . G y coordinate is -2 and H y coordinate is -4
sdfgsdfgs
  • sdfgsdfgs
So the difference between AD is 7-(-1)=8 GH is -2-(-4)=2 what is the ratio of the two differences?
Aizhalee
  • Aizhalee
8:2 ? simplified 4:1 ?
sdfgsdfgs
  • sdfgsdfgs
Yup. so u now know the ratio between the new and old shape: it is 4:1

  • Aizhalee
Thank you so much so how do I use that to find the other end point of the parralelogram ?

  • sdfgsdfgs
What is the difference in X-coordinates between F and G?
Aizhalee
  • Aizhalee
4 and 7
sdfgsdfgs
  • sdfgsdfgs
n the difference is....
sdfgsdfgs
  • sdfgsdfgs
difference is to subtract one from the other...
Aizhalee
  • Aizhalee
7-4=3 **
sdfgsdfgs
  • sdfgsdfgs
Good :) with the ratio, what should be the difference in the bigger shape? Hint: it is 3*something...
Aizhalee
  • Aizhalee
with the ratio being 4:1 and the small shape is 3 spaces apart , the bigger shape has to be 12 ?
Aizhalee
  • Aizhalee
4 times 3 ?
sdfgsdfgs
  • sdfgsdfgs
Great job! Now because that is the difference of the larger shape, all u have to do is adding that back to the X-coordinate of A so -2 + (4 times 3) =?
Aizhalee
  • Aizhalee
im writing these in my notes
sdfgsdfgs
  • sdfgsdfgs
it is -2 + 12...
Aizhalee
  • Aizhalee
sorry with the parenthesis around the 4 +3 i thought i had to multiply
Aizhalee
  • Aizhalee
-2 + 12 = 10
sdfgsdfgs
  • sdfgsdfgs
BINGO n thats the ans u guessed correctly lol
Aizhalee
  • Aizhalee
Thank you sooooooooooooooooooo much !♥ I could hug you right now . I appreciate it :D !
sdfgsdfgs
  • sdfgsdfgs
welcome n hug u back @Aizhalee
