<h2>Answer:</h2>
First of all let's write the slope-intercept form of the equation of a line, which is:
So we just need to find to solve this problem.
Moreover, this problem tells us that Amir drove from Jerusalem down to the lowest place on Earth, the Dead Sea, descending at a rate of 12 meters per minute. So this rate is the slope of the line, that is:
Negative slope because Amir is descending. So:
To find , we need to use the information that tells us that he was at sea level after 30 minutes of driving, so this can be written as the point
. Therefore, substituting this point into our equation:
Finally, the equation of Amir's altitude relative to sea level (in meters) and time (in minutes) is:
Whose graph is shown bellow.

Answer:
21.3%
Step-by-step explanation:
Given that:
Money spent by Jodie for buying English reading books = 25% lesser than that of Claudia
and
Money spent by Gianna is 9% lesser than that of Claudia.
To find:
By what percent, Gianna spent more than Jodie ?
Solution:
Let the money spent by Claudia on her English books = 100
Now, as per question statement:
Money spent by Jodie = 100 - = 75
Money spent by Gianna = 100 - = 91
Now, to find the answer:
Therefore, Gianna spent <em>21.3% </em>more than the amount that was spent by Jodie.
