What is the easiest form to work with when finding the slope of a line and where is the slope located within that form?

y = mx + b is the easiest form to work with when finding the slope of a straight line.

Step-by-step explanation:

There are two forms to find the slope of a straight line.

The first form is known as the slope intercept form

y = mx + b

where m is the slope of the straight line

and b is the y intercept of the straight line

The second form is known as the point slope form

where m is the slope of the straight line

Among the above two, y = mx + b is the easiest form to work with when finding the slope of a straight 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.
