Nolan plots a point at (0, 3) on the y-axis, he uses a slope of 2 to graph another point. he draws a line through the two points.
which expulation represents nolan's line?
y - 2x + 1
y = 2x + 3
y = 3x + 2
y= 3x + 5

y = 2x + 3

Step-by-step explanation:

In order to know the function of a graph you´ll need the slope and a point in the graph, preferible where the graph conects with the Y or X axis, in this case you know that the slope is 2 an the form of the function on Y would be:

M represents the slope

C represents the distance from the 0 that Y has when X is 0, in this case we now that when X is 0, the Y is located at "3", so now we just need to put in the values:

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.
