AB=4
BC=1/4
CD=4
DA=1/4
Yes, quadrilateral ABCD is a parallelogram.
y=2


Explanation
Step 1
The y -intercept of a graph is the point where the graph crosses the y -axis.
so , let's check the graph
therefore, the y-intercept is 2
Step 2
The positive regions of a function are those intervals where the function is above the x-axis. It is where the y-values are positive (not zero)
hence, the function is potive in ( in x axis)

Step 3
negative region
The negative regions of a function are those intervals where the function is below the x-axis. It is where the y-values are negative (not zero).

Answer:
c > -7
Step-by-step explanation:
Isolate the variable c. What you do to one side, you do to the other. Subtract 6 from both sides:
c + 6 (-6) > -1 (-6)
c > -1 - 6
Simplify.
c > (-1 - 6)
c > - 7
c > -7 is your answer.
