Answer 1

1) The image of the point (3,4) in x-axis has the coordinate ?

Answer :-

we know that, when a point is reflected in x-axis,

• x coordinate = remains same .
• y coordinate = becomes negative.
• Image of point P(x, y) = P'(x, -y).

then,

→ Image of Point (3 , 4) = (3 , -4) .

2) Abscissa the points on y-axis is = Zero .

3) The sum of probabilities of an impossible event = Zero .
