Answer:
Jane is not correct.
Step-by-step explanation:
Jane must have complete several examples using positive numbers. That conclusion does not apply for negative numbers.
Let's see an example:
Given the number 5:
- its opposite number is: -5
- the opposite of this opposite number: is 5
Note that is the same number and it is positive.
However, if we check the same situation with a negative number:
Given the number -3:
- its opposite number is: 3
- the opposite of this opposite number: is -3
In conclusion, Jane's conclusion is wrong. The opposite of the opposite number is not always a positive number.

10
Step-by-step explanation:
you do minus so you get 10
Answer:
y = - 2x - 13
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 2x - 5 ← is in slope- intercept form
with m = - 2, thus
y = - 2x + c ← is the partial equation of the line
To find c substitute (- 4, - 5) into the partial equation
- 5 = 8 + c ⇒ c = - 5 - 8 = - 13
y = - 2x - 13 ← equation of line
