What is an equation of the line that passes through the points (−8,2) and (−4,−3)?

y = - x - 8

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

To find m use the slope formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (- 8, 2) and (x₂, y₂ ) = (- 4, - 3)

m = = -

y = - x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

using (- 4, - 3), then

- 3 = 5 + c ⇒ c = - 3 - 5 = - 8

y = - x - 8 ← equation of line

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.
