In slope-intercept form, what is the equation of the line passing through the points (3, 17) and (7, 25)?

a. y = −2x + 23
b. y = 2x − 11
c. y = −3x + 26
d. y = 2x + 11

D. y = 2x + 11

Step-by-step explanation:

The slope-intercept form is:

where m is the slope of the line and b is the y-intercept.

To find the slope:

Then, the slope-intercept form so far is:

Now, to find the y-intercept, you're going to choose one of the two points given and substitute it into the equation (the first coordinate into the x, and the second coordinate into the y), and then isolate the b. In this case, let's use the first point (3, 17):

Substituting, you're left with the final slope-intercept form equation of the line passing through (3, 17) and (7, 25):

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.
