Here's a graph of a linear function. Write the equation that describes that function.
Express it in slope-intercept form.

  y =  

Step-by-step explanation:

We could find two points on graph to find the slope of the graph since we already know its y-intercept.The y-intercept is when x is 0.

We could find the points (0,-3)   and  another points ( 3,-2) to solve for the slope we will find the difference in y and divide it by the difference in the x values.

(0,-3)

(3,-2)    

y     -3 - (-2) = -1

x      0 - 3 =   -3  

-1/-3  =  1/3

so now we know the slope is 1 thirds or 1 over 3 and the y intercept is -3

so the equation will be      y = 1/3x - 3

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.
