The measure of steepness of inclined path is termed as:
Slope
Inclination
Both(b)&(c)
Gradient

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

Equation of Y-axis is
y = c
x = c
x = 0
y = 0

The distance of the point (3, 7) from x-axis is
-7
7
-3
3

Which one is equation of straight line perpendicular to x-axis?
y = k
x = k

If a line lis parallel to x-axis then slope is:
0
1
-1

Equation of a straight line passes through P(a,b) and parallel to y-axis is:
y+b=0
y=b
x+a=0
x=a

If the line l is parallel to y-axis, then the slope of 1 is _________
0 degree
Undefined
90 degree
180 degree

The straight line passing through the point of intersection of the straight lines x – 3y + 1 = 0 and 2x + 5y – 9 = 0 and having infinite slope and at distance 2 units form the origin has the equation
y = 1
None of these
x = 2
3x + y – 1 = 0
