Question

What is the equation of the graph shown?

Answer 1

Answer:

since the line is parallel to y axis

so it's equation is y=-4

Answer 2

Answer:  x = 1

Step-by-step explanation:

The equation for any vertical line parallel to the y-axis on a graph cannot be expressed using 'y'. Hence the equation x=a can be used, where a is the x-intercept of that graph. In this case, since x always takes the value 1, the equation is x = 1.
