Amber tried to evaluate an expression step by step. \quad\begin{aligned} &-3-(-5)+4 \\ =&-3+5+4&\green{\text{Step } 1} \\ \\ =&-3+9&\blue{\text{Step } 2} \\ \\ =&\:\:\:6&\purple{\text{Ste p } 3} \\ \\ \end{aligned} = = = −3−(−5)+4 −3+5+4 −3+9 6 Step 1 Step 2 Step 3 Find Amber's mistake. Choose 1

See below

Step-by-step explanation:

Amber should’ve added -3 and 5 first instead of adding 5 and 4 because if there are multiple terms with addition and subtraction/multiplication and division, the one that is first should be evaluated first  

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
