As the line is vertical, it has same points for x - coordinates. And it never changes for whole line.
We know, slope (m) = y2 - y1 / x2 - x1
As x2-x1 = 0 [ x2=x1 ]
m = y2-y1 / 0
m = undefined
So, y = mx + c
y = c
In short, Your Answer would be y = c
Hope this helps!
Answer: a)
<u>Step-by-step explanation:</u>
Matrix multiplication is the sum of Row 1 (of first matrix) x Column 1 (of second matrix) ...repeat for each row.
Transpose means to switch the rows to columns.

Answer:
The equivalent factored form of this equation is (x² + 49)(x - 6)
Step-by-step explanation:
<em>x³ - 6x² + 49x - 294</em>
First, group the first and second terms together and group the last two terms together.
<em>(x³ - 6x²) + (49x - 294)</em>
Find the greatest common factor of both parentheses and factor them.
x²(x - 6) + 49(x - 6)
Now, since the two terms in the parentheses are the same, then we have factored the equation correctly.
So, the factored form of the equation is (x² + 49)(x - 6)
