What is the slope of the following equation -3y=-18x+9

You need to convert it to slope/intercept form ( y = mx + b) where m = slope.

-3y = -18x + 9

divide through by -3:-

y = 6x - 3 so the slope = 6 (answer)

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.

a box 3 3/4 feet long or 4+ feet.
