Find the slope of the line that passes through (4,7) and (1,10). Simplify your answer and write it as an improper fraction, proper fraction or an integer.

Step-by-step explanation:

co-ordinates = (4,7) and (1,10)

Slope = (y² -y¹) / (x² - x¹)

= (10-7) / (1-4)

= 3 / -3

= -1

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.

answer: i think it is (1,-2)
