There are two ways to equate a straight line. We first have y=mx+b. Then, we have (y-y₁)=m(x-x₁). Both work fine and have similar variables, but the numbers are mixed around a bit. Your equation clearly shows the second form of equation. As our equation has x-x₁ on the right, we can notice that x+1 must mimic that, so x+1=(x-x₁). As x-(-1)=x+1, we can only assume that x is -1. Looking at the points given to us, y must be -2, so we have y-(-2)=y+2, so 2 fills in the leftmost open box. To find the slope, or m, we must take
from points (x₁, y₁) and (x₂, y₂). It doesn't matter which point is (x₁, y₁) , but it matters that the y₁ corresponds to the x₁. Thus, we have our slope as

Answer:
-5 and 3.
Step-by-step explanation:
-5x3=-15 -5-3=-2
Answer: Divide each side by '10'. x2 = 9 Simplifying x2 = 9 Take the square root of each side: x = {-3, 3
Step-by-step explanation:
First, 
, and if we multiply 
by 
we get
Subtracting this from the numerator gives a remainder of
Next, 
, and if we multiply by 
we have
and subtracting this from the previous remainder, we end up with a new remainder of
Next, 
, and if we multiply by 
we get
Subtracting from the previous remainder, we get a new remainder of
which contains no more factors of 
, so we're done.
So,
