1.	65. What is the reflection of thepoint (- 1, 3) in the line x--4?
Answer» Line x=-4 is a straight line parallel to y-axis and at a distance of 4units in negative direction of x- axis. Point (-1,3) is 3 unit away from given line x=-4. therefore distance of imagefrom the line is also 3 units. Thus distance of image from y-axis = 3+3+1=7 Units in negative direction of x - axis. Thus reflection of point (-1,3) in the line x=-4 is (-7,3) , Answer.

Answer»

Line x=-4 is a straight line parallel to y-axis and at a distance of 4units in negative direction of x- axis.

Point (-1,3) is 3 unit away from given line x=-4.

therefore distance of imagefrom the line is

also 3 units.

Thus distance of image from y-axis = 3+3+1=7

Units in negative direction of x - axis.

Thus reflection of point (-1,3) in the line x=-4

is (-7,3) , Answer.
