Answer:
-3
Step-by-step explanation:
To find the slope given two points
m = (y2-y1)/(x2-x1)
= (-5-7)/(-4- -8)
= (-12)/(-4+8)
=-12/4
= -3
Answer:
Step-by-step explanation:
Draw your figures the same way as I did, and see if you understand the explanations before writing them down. It's most important to learn from your work :)
Consider the equation:

Subtracting '4' from both the sides of the equation, we get as


Squaring on both the sides of the equation, we get


Subtracting '2' from both the sides of the equation, we get

x=14
Since, An extraneous solution is a solution that arises from the solving process that is not really a solution at all. But, in this equation x=14 is the solution of the given equation.
Hence, it is not an extraneous solution.
