Choose the graph that correctly corresponds to the equation y = −4. graph of a horizontal line through the point (0,4) graph of a vertical line through the point (4,0) graph a horizontal line through the point (0, negative 4) graph of a vertical line through the point (negative 4,0)

graph a horizontal line through the point (0, negative 4)

Step-by-step explanation:

The equation of line is  y = -4.

The equation of horizontal line is given by y = k. This line always passes through the point (0,k).

Here, k = -4

Hence, the line passes through the point (0,-4).

We can see this in the attached graph as well.

Therefore, the graph of the line is horizontal and passes through the point (0,-4)

third option is correct.

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
