Question

Figure ABCD is a parallelogram. If point C lies on the line y= -1, what is the x-value or point C?

Answer 1

Answer: D.4

Step-by-step explanation: in the begin of this question it says the the figure is a Parallelogram so that is one hint then the second is that point C line on the line y=-1 (which is the dotted line going through y(-1)) so if you were the place point C on 1 that wouldn't be the smartest because the figure wouldn't be a parallelogram anymore. but as you place point C x coordinate on 4 it makes a parallelogram. I guarantee that this is the answer

Just in case you dont know what a parallelogram looks like:

Answer 2

Answer:

The correct answer is option D.  4

Step-by-step explanation:

Points to remember

Opposite sides of the parallelogram are equal.

From the figure we can see that,AB and CD are opposite sides.

Therefore AB = CD

To find the length of AB

From the figure we get, AB = 4 units

Therefore CD = 4 units

To find the x coordinate of point C

y coordinate is -1

x coordinate is 4 units from point D

x coordinate of D is 0, therefore x coordinate of C = 0 + 4 = 4

The correct answer is option D. 4
