Answer:
Option A
Step-by-step explanation:
We can try to factorize all the options one by one.
For A:
We can see that the quadratic expression cannot be solved by factorization as the factors at the end of factorization are not equal in both brackets. So Option A is the correct answer for the given question.
Moreover we can also note that all the other quadratic expressions can be factorized ..

Answer:
The slope of the line is and the equation of the line is
.
Step-by-step explanation:
From table we understand that slope of the line is constant, that is, for each change of there is one and only change in
, fulfilling the main characteristic of a line and we can determine the slope for every point of the line by means of the following expression:
(1)
Where:
- Initial and final x-coordinates of the line.
- Initial and final y-coordinates of the line.
If we know that and
, then the slope of the line is:
From graph we conclude that x-intercept of the line is . Hence, the equation of the line is
and we proceed to plot the expression with the help of a graphing tool.
