Answer:
3
Step-by-step explanation:
Dilated has the meaning of getting larger. So in this case, if it has any meaning at all and the answer is "no answer given" then all you have to do is look at the y intercept.
The shorter line has a y intercept of 1
The longer line has a y intercept of 3
Therefore the dilation factor is 3
However if your teacher is a stickler for a better proof, then you could compare lengths.
Shorter line
Two end points
(-6,-3) (6,5)
Distance = sqrt( (-6-6)^2 + (-3-5)^2 )
distance = sqrt (144 + 64)
distance = sqrt(208)
distance = 14.42
Longer line
(-12,-5) (24,19)
distance = sqrt(24 - - 12)^2 + (19 - -5)^2 )
distance = sqrt( 36^2 + 24^2)
distance = sqrt (1296 + 576)
distance = sqrt(1872)
distance = 43.27
The best answer is =3
