Answer:
3
Step-by-step explanation:
Parallel lines have equal slopes, thus
line AB is parallel to line CD
Answer: the second one i may be wrong but i can relate to you ❤
If the preimage point is (5,0) and the image point is (10,0)
then the scale factor is k = 2
Basically the coordinates of the old point have doubled (multiplied by 2)
x = 5 is the old x coordinate
x = 10 is the new x coordinate (5*2 = 10)
y = 0 is the old y coordinate
y = 0 is the new y coordinate (0*2 = 0, no change)
The answer is A: 5
Any answer with 0 doesn't work because then the denominator would be 0 as well, and negative 5 does not make the numerator equal to 0.
