The answer is
Step-by-step explanation:
The slope of a line given two points can be found by using the formula
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(-18, 13) and (-14, -20)
The slope is
We have the final answer as

Answer:
(0,1) is the unique solution of the system .
Step-by-step explanation:
The given sets of equations are
x + 2y = 2
x - 2y = -2
Compare the equations with ax + by = c
Here, we get a1 = 1, b1 = 2 and c1 = 2
and a2 = 1, b2 = -2 and c2 = -2
Now, as we can see ,
Here,
Hence, the system has UNIQUE SOLUTION.
And, (0,1) is the unique solution of the system
x + 2y = 0 + 2(1) = 2 = Right side
and x - 2y = 0 - 2(1) = -2 = Right side
