Please find the slope and the equation.

and step by step explanation PLEASE.

Explanation:

Two points on this diagonal line are (0,-4) and (1,-3)

Let's apply the slope formula to get the following

m = (y2-y1)/(x2-x1)

m = (-3-(-4))/(1-0)

m = (-3+4)/(1-0)

m = 1/1

m = 1

The slope is 1. We can think of it as 1/1 to indicate "go up 1, and over to the right 1". In other words, slope = rise/run = 1/1.

Note how the graph crosses the y axis at -4, so this is the y intercept.

Since the y intercept is -4, this means b = -4

So with m = 1 and b = -4, we go from y = mx+b to y = 1x+(-4) which simplifies to y = x-4

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.

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.
