Answer:
(3,4)
Step-by-step explanation:
The amount of steps applied from the reflection line to the point would be also applied inversely to the image point (after reflection).
From y=x to (4,3), it goes 1 down and also goes 1 right. (NOTE: It does not go down and right. Instead, it goes <em>either</em> down and right)
So now inverse that to make 1 up and also going 1 left.
Answer:
option 2
Step-by-step explanation:
consider the coordinates A (- 3, 4 ) and A' (- 1,
)
since the dilatation is centred at the origin, then corresponding coordinates are multiples/ divisors of each other, then image to original gives scale factor.
scale factor =
=
=
and
= 
similarly B (1, - 2 ) and B' (
, -
)
=
and
= 
Answer:
27,9
Step-by-step explanation:
9x3=27
Answer:
C: Either the mean or median; both are 5
Step-by-step explanation:
MEAN: 5+2+4+8+6= 25 = 25/5= MEAN IS 5
MEDIAN: put it in order: 2,4,5,6,8
cross out 2,8,4,6
left over number is 5
So median is 5
Answer:
The point (-4,5) is on the line
Step-by-step explanation:
You can replace the x and y values to determine if it is a true statement
First Statement
5= 2(-4)+13 -> 5= -8+13 -> 5=5 true
Second Statement
-4=2(5)+13 -> -4= 10+13 -> -4 ≠ 23 false
You can automatically eliminate the next two answers because you already found that the first statement is true and because you can find points using an equation.
