The equation to the straight line which passes through the point (2, 9) and makes an angle of 45 degree with x-axis is
y – x + 7 = 0
x + y + 7 = 0
x – y + 7 = 0
None of these

x = c is a line
Perpendicular to y-axis
Parallel to x-axis
None of these
Perpendicular to x-axis

The centroid of a triangle divides each median in the ratio
2:01
1:03
1:02

The distance of a point P(x,y) from x-axis is:
x
x+y
|y|
x-y

The distance of a point P(-2,-3) from x-axis is:
2
-3
-2
3

If a point P(x,y) is on y-axis then
x=0
x must be -ve
x must be +ve
y=0
