Answer:
slope = -2
Step-by-step explanation:
Slope = 
![= \frac{6-[-4]}{-2-3}\\\\= \frac{6+4}{-2-3}\\\\= \frac{10}{-5}\\\\= -2](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B6-%5B-4%5D%7D%7B-2-3%7D%5C%5C%5C%5C%3D%20%5Cfrac%7B6%2B4%7D%7B-2-3%7D%5C%5C%5C%5C%3D%20%5Cfrac%7B10%7D%7B-5%7D%5C%5C%5C%5C%3D%20-2)
A dependent means t-test determines if the differences between scores on the pretest and post-test measures differ significantly from Zero(0).
Benefits of pre-test measurements
This design is superior to the post-test-only control design because it adds pre-tests. Addition of pre-test: Improve your design ability to detect effects. You can investigate the impact of interventions on various sublevels of pretesting.
The design of the pre-test and post-test is similar to the in-subject experiment. In this experiment, each participant is first tested in control conditions and then in therapeutic conditions.

I’m sorry, but how do I see you’re recent questions? I’d love to help! However I have no clue how to find the questions.
Hello!
<u><em>Answer: x=-9 *The answer must have negative sign*</em></u>
Explanation:
First you had to do is subtract by 4 from both sides of an equation.
Then, simplify.
Divide by -4 both sides of an equation.
Finally simplify.
It change positive to negative sign.
Hope this helps!
Thanks!
Have a great day!

The first step of solving this is to isolate the variable y in the first equation.
3x - y = -2 Subtract -3x from both sides
- y = - 3x - 2 Divide both sides by -1
y = 3x + 2
Now, substitute that y value into the second equation.
2x^{2} - y = 10 Substitute
<span>2x^{2} - (3x + 2) = 10 Multiply all of the numbers in the parentheses by -1
2x^{2} - 3x - 2 = 10
</span>
<span>So the correct answer choice is D) 2x^{2} -3x - 2 = 10.</span>
