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

Question

A. x = 4

B. x = -4

C. y = -6

D. y = 6

E. y = 0

Answer 1

Answer is D

 

as Equation of line is Y=my+b

so if m=0 and x=4and y=6

substituning in above equation 

6=4.0+b we get b=6

and equation is again y=mx+b so m =0 and y =b or y=6
