What is an equation of the line that passes through the points (8, -8) and (-5, -8)

y = -8

Step-by-step explanation:

Instead of trying to find the slope of the line through these two points in the usual rise/run fashion, note that y does not change as we progress from x= -5 to x= +8.  This tells us immediately that this line is a horizontal one:  y = -8.

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.
