I need help with slope (8th grade)

(y1-y2)/(x1-x2)

Step-by-step explanation:

if you have two points from the graph then you can use them to find the slope, for example:

(2,3) and (0,5)

you would take the first point and put it in a fraction (and the second point) but the x goes on the bottom and the y goes on the top:

3/2 and 5/0

Next you put them together minusing one of the equations, but make sure that the two coordinates line up (it doesn't matter which one, in the order):

3-5/2-0

Then you solve:

-2/2

-1

which means that -1 is the slope for this

(the "/" is a fraction bar, in case you didn't already know that)

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.
