What is the equation of the line that passes through the point (9, -7) and has a slope of zero? A. x=9 B. x= -7 c. y=9 D y = -7​

Respuesta :

Answer:

D. y = -7

Step-by-step explanation:

Given:

x1 = 9

y1 = -7

slope (m) = 0

Solution:

y - y1 = m ( x - x1 )

y - (-7) = 0 ( x - 9 )

y + 7 = 0

y = -7
