The Cowboys gained 8 yards during the first
down and lost 3 yards
during the second
down. How many
yards to they have to
run to make another
first down?

ratio is 2 : 9

the answer is three

13.5 : 3

answer: the correct option is d.

explanation:

it is given that the triangle j'k'l' shown on the grid below is a dilation of triangle jkl using the origin as the center of dilation.

from the given graph it is noticed that k(4,8) and k'(2,4). let origin is defined by o and scale factor is defined by k, then

    (1)

distance formula,

put these values in equation (1).

therefore scale factor is     and option d is correct.
