On a coordinate plane, a triangle is reflected across y = negative 2. Which is the reflection line for the transformation shown?
A: x-axis
B:y-axis
C:x=-2
D:y=-2

The answer will be D.y=-2

Step-by-step explanation:

The reflection line is the fixed line that a shape or figure is reflected across of. The problem tells you that the triangle is reflected across y=-2

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.
