What is the slope sf the line below be sure to scroll down firs to see all (-6,3) (3,-9)

To find the slope(m), use the slope formula:

      And plug in the two points on the line

(-6, 3) = (x₁, y₁)

(3, -9) = (x₂, y₂)

  (two negative signs cancel each other out and become positive)

    Simplify the fraction

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.
