Answer:
2 is not function because 1 has no unique image
If we have two coordinates that are in the line we can find the slope with this equation:
So now we replace the coordinates so:
Now with the slope and any point we can find the intercept in the y axis by replacing x=0 so:
So the equation is:
Every mile is 5,280 feet, so all you have to do is use this equation. 5,280 * 2.5
The operation that reverses the effect of another operation.
Example:
Addition & Subtraction are Inverse Operations.
Start with 7, then add 3 we get 10, now subtract 3, and we get back to 7.
Another:
Example: Multiplication & Division are inverse operations.
Start with 6, multiply by 2, we get 12, now divide by 2, and we get back to 6.
Hope this helps!!!!!!!
