Answer:
Step-by-step explanation:
For this, we kind of have to test points to solve it. First, we can test theh interval x<= -2. Plug in -2 and we get a negative value which works. Next, let's try -2<x<0. Plug in -1 and get a positive value which doesn't work.
Next try 0<=x<=7. Plug in any number like 4 and get a negative value which works.
Finally, try x>7. Plug in 8 for example and you would get a positive value. So the solution is
x <= -2 OR 0 <= x <= 7
A)
The slope-intercept form:

m - slope
b - y-intercept
The formula of a slope:

We have the points (2, 5.1) and (-1, -0.5). Substitute:

Therefore we have:

Put the coordinates of the point (-1, -0.5) ot the equation:

<em>multiply both sides by 2</em>
<em>add
to both sides</em>
<em>divide both sides by 2</em>

Answer: 
-------------------------------------------------------------------------
B)
We have the points (-2, 3) and (3, -4).
Calculate the slope:

Therefore we have:

Put the coordinates of the point (-2, 3) to the equation of a line:

<em>subtract
from both sides</em>

Answer: 
Answer:
to my opinion it should be
They are a zero pair
They are opposites
They are the same distance from zero
They are equivalent
hope i helped
