What is the equation for the horizontal line through the point (9,6)?
for any point (a,b), a is the x coordinate, vertical line b is the y coordinate, horizontal line where these 2 lines intersect you have the coordinate (a,b) now for the point (9,6) the equation for the horizontal line is: y = 6 and for the point (7,9) the equation for the vertical line is: x = 7 hope this was helpful, have fun and all the best!
