I NEED HELP ASAP PLEASE AND THANKS.

b=320; slope=-30

Step-by-step explanation:

if you look along the y-axis find the spot that the line intercepts and then that's b

now for the slope

find two points on the line, i chose(8 , 120) and (4 , 240)  

use the slope formula: y2-y1 over x2-x1

240-120=120 and 4-8= -4

so the slope is 120/-4 and that can be simplified to 30/-1 or -30

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.
