Answer:
coordinates of vertex M is (x, y) = (2, -2)
Step-by-step explanation:
Since JKLM is a parallelogram, this implies that JK parallel to LM and KL parallel to JM. This means that
Slope of JK = slope of LM
And
Slope of KL = slope of JM
From equation (i) and (ii) we get
Put the value of x in equation (ii) we get
So, the coordinates of vertex M is (x, y) = (2, -2).
Answer:
up, down
Step-by-step explanation:
It is an even-degree polynomial. Therefore, the start of domain is the opposite the end of domain.
Meaning if the graph starts by decreasing, the graph will end by increasing.
Because the coefficient of highest degree is in negative. Therefore, the graph starts from negative infinity, increasing. The graph will end in positive infinity but decreasing.
Therefore, the answer is first choice.
