Question

Which of the following is the equation of a line that has a slope of zero and passes through the point (4,6)?

x = 4

x = -4

y = -6

y = 6

y = 0

Answer 1

y = mx+b


6 = (0)(4)+b


6 = 0+b


6 = b


b = 6


So the equation of the line is y = 0x+6 which can be simplified to y = 6


So the answer is choice D
