Question

What is the equation of a horizontal line passing through the point (−7, 5)?

y = 5

y = −7

x = 5

x = −7

Answer 1

all points on horizontal lines are equi-distance from x axis

distance from x axis is measured by y co-ordinate

so all horizontal line will have same y co-ordinate

hence equation of horizontal line will be of the form y =c

Answer 2

where 'c' is the y co-ordinate of any point on that line

Answer 3

correction :
so all points on horizontal line will have same y co-ordinate

Answer 4

wait so its y=5 ?

Answer 5
