Calculate the function values for x = 2

Look at the picture.
Answer:

Answer:
x = 0
Step-by-step explanation:
6 ( x + 1 ) - 5x = 8 + 2 ( x - 1 )
6x + 6 - 5x = 8 + 2x - 2
-x = 0
x = 0
Answer:
Is that the whole problem

Answer:
The gradient of a line is given by
.
Any 2 points of a vertical line would have the same x-coordinate. Thus when you simplify the denominator, you would end up with a zero. If you enter that into your calculator, no matter what you numerator is, you would get a Math error. This is because you cannot possibly divide a number by zero. Thus, the gradient is undefined.
