The slope is the ratio between the change in the y and x values. When you write a line as 
, the slope is the coefficient 
. So, the slope of the first graph is 405, which means that the first plane flies with a speed of 405 miles per hour.
Similarly, from the table we can see that each time you increase x by 1, the distance traveled increases by 435. So, the slope of the second graph is 435, which means that the second plane flies with a speed of 435 miles per hour, and is thus faster.
-24
-66+42
=-24 since it is negative
You literally just need to click yes then call it a day it’s simple don’t worry too much :D
Hi there!
There is an initial cost of $210,000 (which you're just going to pay once)
Then it costs $500 per day to operate.
The number of days is represented by "x".
Your equation in function notation should look like this :
f(x) = 500x + 210,000
There you go! I really hope this helped, if there's anything just let me know! :)
