We are asked to find the slope of this graph; we are provided with two points:
- What we need in order to find the slope are two points and the slope formula.
Here's the formula:
Where
y2 and y1 are y-coordinates
x2 and x1 are x-coordinates
Substitute the values:
Simplify!
Simplify more!
Hope it helps you out! :D

Given: 
Find: 
Solution: We need to plug in the value -2 into every variable x that we have in the expression and simplify to get the solution.
<u>Plug in the values</u>
<u>Simplify</u>
- <u />
Therefore, the ordered pair that would match would have a x-coordinate of -2 and a y-coordinate of 4 producing (-2, 4) which matches option A.
Answer:
The study involves one or more treatment groups and a control
group.
Answer:
1. 2x can be seen as +2x therefore when you put it as +2x-5x the answer will be - 3x
2. +3a+2a also equals +5a
3. - 5 is left alone and there is no other similar expression
Put them together the answer becomes
-3x+5a-5
It doesn't have to be the same order of format but the numbers must be as such
