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?

    OK all 4 choices have 7 as the y-coordinate. so no need to worry about that right?

    look at A and D, what is the difference between their y-coordinates? then look at G and H, what is the difference there?

    A y coordinate is 7 and D ycoordinate is -1 . G y coordinate is -2 and H y coordinate is -4

    So the difference between AD is 7-(-1)=8 GH is -2-(-4)=2 what is the ratio of the two differences?

    8:2 ? simplified 4:1 ?

    Yup. so u now know the ratio between the new and old shape: it is 4:1

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

    Good :) with the ratio, what should be the difference in the bigger shape? Hint: it is 3*something...

    with the ratio being 4:1 and the small shape is 3 spaces apart , the bigger shape has to be 12 ?

    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) =?
