Question

Choose the graph that correctly corresponds to the equation x = −4. (5 points)

Select one:
a. graph of a horizontal line through the point (0,4)
b. graph of a vertical line through the point (4,0)
c. graph a horizontal line through the point (0, negative 4)
d. graph of a vertical line through the point (negative 4,0)

Answer 1

x = -4

this is a vertical line through the point (-4,0)

Answer 2

Option D is true. ( graph of a vertical line through the point (negative 4,0) )

Explanation:

We have to choose a graph such that it corresponds to the equation x= -4.

We know that the graph of x= -4 is a straight line which passes through (-4,0) such that the value of 'x' is constant all over the real line and the value of y may vary over the real line and such a line is a vertical line parallel to the y-axis.

The graph of such function is attached to the answer.

Hence, option D is correct.
