4. Triangle XYZ is graphed on a coordinate grid with vertices at X(-2,5), Y(-1,-7), and Z(2,-4). Triangle XYZ is dilated by a scale factor of u with the origin as the center of dilation to create triangle X'Y'Z'. Which ordered pair represents the coordinates of the vertex Y'? A. (-1 + U, -7 + u)
(Yellow Hearts)
B. (-1 -u, -7 - u) (Red Hearts)
C. (-1u, -7u) (Pink Hearts)
D. (-7,-) (Green Hearts)​

step-by-step explanation:

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.
