If ? is the indination of non- vertical line “I” then its slope or gradient is:

cos?

tan?

cot?

sin?

Tow line with slopes m₁ and m₂ are perpendicular if:

m₁m₂ = -1

m₁ = -m₂

m₁m₂ = 1

m₁ = m₂

Equation of the line parallel to x + 3y – 9 = 0 is

3x + 9y + 7 = 0

2x – 6y – 18 = 0

x – 3y + 9 = 0

3x – y – 9 = 0

y = 2x + 3 is the

Two points form

Intercepts form

Pont slope form

Slope intercept form

circum centre

centroid

in centre

orthocentre

The lines lying on the same plane are called

Concurrent

Coplanar lines

Parallel lines

Collinear lines

If a = 0, then the line ax + by + c = 0

Parallel to y-axis

Passes through origin

Parallel to x-axis

Perpendicular to x-axis
