Answer:

Step-by-step explanation:
Let
represent the real numbers.
For the first part, all real numbers less than or equal to 9 in algebra is
.
For the second part, all real numbers greater than or equal to 7 in algebra is
.
To combine both inequalities, it would become

Step-by-step explanation:
6-8/1- -1 = -2/2 = -1 is the slope
y - 8 = -1(x+1)
Answer:
First option
Step-by-step explanation:
Hi there!
The "constant additive rate of change" means a constant slope.
The slope is
.
First of all, if the slope is constant, then we know immediately that it must be a linear function, a line. The change in <em>y</em> is forever the same according to the change in <em>x</em>. Knowing this, the second option is for-sure wrong (it's not a straight line).
Now, let's look at the first option. It is a linear function, which means it has a constant slope. However, we're given that the slope is
. This means that for a line, whenever it travels 4 units to the right, it travels 1 unit <em>down </em>(it travels down whenever the slope is negative and up whenever the slope is positive).
This is the exact case for the first option. Look at the point (-2,2) on the line. When we move 4 units to the right of that point, The line would have moved 1 unit down. We would reach the point (2,1).
Therefore, the correct answer would be the first option.
I hope this helps!
