Answer:
Step-by-step explanation:
The equation of a straight line can be written as 
.
With the pair of coordinates (coordinates are written in the form 
) , the following can be written:
To solve for a variable, we can use elimination:
(subtract the second equation from the first)
(
is eliminated)
To solve for the other variable, we can use substitution:
is the linear equation for the line that passes through the points 
and 
Answer:
The first question:
x = -1
Step-by-step explanation:
Step 1 :
Pulling out like terms :
1.1 Pull out like factors :
-x - 1 = -1 • (x + 1)
Equation at the end of step 1 :
Step 2 :
Solving a Single Variable Equation :
2.1 Solve : -x-1 = 0
Add 1 to both sides of the equation :
-x = 1
Multiply both sides of the equation by (-1) : x = -1
One solution was found :
x = -1
