Answer:
This one is pretty straightforward.
x=-5/yz
For 2 figures to be similar, their corresponding sides must be proportional and their corresponding angles must be congruent.
While we see that the sides are all proportional, the corresponding angles are not congruent, therefore the correct option is the third option.
Your brother is correct, because the sequence is increasing.
Y = -3x + 12...the slope here is -3...a parallel line will have the same slope.
y = mx + b
slope(m) = -3
(-1,6)...x = -1 and y = 6
now we sub and find b, the y int
6 = -3(-1) + b
6 = 3 + b
6 - 3 = b
3 = b
so ur parallel equation is : y = -3x + 3 <==
