Episode 17 – Different types of line equations

European section, season 01

(2)

General form

ax + by + c = 0

Any line has an equation of this form, and in fact many as it’s always possible to apply a

coefficient to the whole equation.

(3)

Slope-intercept form

y = mx + p

m is the slope ; p is the intercept.

This form exists and is

unique for any line not

parallel to the y -axis.

(4)

Point-slope form

yy 0 = m(xx 0 )

m is a the slope ; (x 0 , y 0 ) are the

coordinates of a point on the line.

This form exists for any line not parallel to the y -axis.

It’s not unique as any point

can be used.

(5)

Intercept form

x q + y

p = 1

p is the y -intercept ; q is the x-intercept.

This form exists and is

unique for any line not

parallel to an axis.

Rule 2 : When a line of the section plane is in a face, and a third point is on a face with an edge in common, you can draw the intersection of the line with the common edge..

To find the coordinates of the intersection of a plane with a line (if it exists), just solve the system made of a cartesian equation of the plane and a set of parametric equations

Erdös asks us to imagine an alien force, vastly more powerful than us, landing on Earth and demanding the value of R (5, 5) or they will destroy our planet. In that case, he claims,

Planar and plane graphs.. Plane

For any polygon P in a lattice, we note B P the number of points on its border and I P the number of points strictly inside the polygon..

Addition and multiplication in the set Z [i ] follow the same rules as addition and multiplication of integers but “real parts” and “imaginary parts” cannot be mixed up

The set Z[i] is a unique factorization domain : any Gaussian integer can be written as a product of Gaussian primes, and this. decomposition is unique except for reordering
