Nour drove from the Dead Sea up to Amman and her altitude was 409 meters below sea level. When she arrived in Amman 2 hours later, her altitude was 1000 meters above sea level. Let y represent Nour's altitude(in meters) relative to sea level after x hours

y=  704.5x - 409

Step-by-step explanation:

Complete question is : . Complete the equation for the relationship between the altitude and number of hours.

SOLUTION

By plotting altitude on y-axis and time or duration of travel on x-axis of the graph, we will have the the location of Nour at t = 0 will be represented by (0, -409)

when t = 2 hours location points will be  at (2, 1000).

As you know, at a constant rate her altitude is increasing , we will have a linear graph with equation y = mx + b --> eq(1)

Slope of the line is given by:

m= (y-y') / (x-x') => (1000+409)/(2-0)

m= 704.5

y-intercept 'b' is -409

Therefore, the eq(1) will become

(1)=> y=  704.5x - 409

Where, 'y' represents Nour's altitude(in meters) relative to sea level after 'x' hours

c

step-by-step explanation:

it isn't d, because the interquartile range is from 27-57. and the interquartile range is basically half the data, it's pretty obvious.

it isn't b, because like i said earlier, the interquartile range is from 27-57. 57-27 is 30. the real range has to be longer

not a either. although it looks like it, 3/4 of the data is not greater than 27. but if c is wrong than this should be correct

the correct answer is c, because 13 is the point in which the plot starts

triangle abc is reflected on the line x=-6.5 then reflected again on the x axis
