Answer:
The answer is A
Step-by-step explanation:
By looking at the graph, the y-intercept is -1. So, the answer must be A or C.
Then we can look at the the graph, you can see the line is left up right down. So the equation will be negative, which is A.
26 = 3x - 2 - 7x
26 + 2 = -4x
28 / -4 = x
x = -7
Best answer me please!
Answer:
It would be undefined if the line is vertical.
Step-by-step explanation:
When put in matrix form, the coefficients of
... 3x -2y = 7
... x + 4y = 2
look like
![\left[\begin{array}{cc}3&-2\\1&4\end{array}\right]](https://tex.z-dn.net/?f=%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D3%26-2%5C%5C1%264%5Cend%7Barray%7D%5Cright%5D%20%20)
The determinant is 3×4 - 1×(-2) = 14.
