Choose the equation of the line in slope-intercept form. Parallel to the x-axis and has the point (-1,9).

A. x = -1
B. y = 9
C. y = -1
D. x = 9

B)   y = 9

Step-by-step explanation:

Equation of a line in slope-intercept form:  y = mx + b

(where m is the slope (gradient) and b is the y-intercept)

If the line is parallel to the x-axis, the slope is zero.

Therefore, y = (0)x + b

⇒ y = b

We are told that the line passes through point (-1, 9).  Therefore, the y-intercept is 9.

So the equation of the line is:  y = 9
