Answer: (A) y=-2x
Step-by-step explanation:
Lets plug in the point (2,-4) for each equation.
-4=-2(2) this is correct
-4=2*2
-4=4 This cannot be true
-4=-2+3 =-4=1 This is false
Lastly, -4=2-4 this is false because -4 can't equal to -2.
So, A is the answer
Answer:
used formula to find Area of parallelogram
area of parallelogram =b× h
Step-by-step explanation:
solution :
given ,
h = 7cm
b = 9 cm
we know ,
Area of parallelogram = b× h
=63cm²
Solution
The reflection is a rigid transformation. This does not affect the length of a line segment.
Therefore, the line segments are equal.
Hence, LM = L'M'

Answer:
slope = k/2
Step-by-step explanation:
The slope formula is useful for finding slope.
m = (y2 -y1)/(x2 -x1)
m = (5k -7k)/(-3 -1)
m = -2k/-4
m = k/2
The slope is k/2.
