One of the most important properties of a straight line is in how it angles away from the horizontal.
y = ( 2/3 )x – 4. 
Slope

The other format for straightline equations.
* Find the equation of the straight line that has slope m = 4 and passes through the point (–1, –6). y – y1 = m(x – x1) y – (–6) = (4)(x – (–1)) y + 6 = 4(x + 1) y + 6 = 4x + 4 y = 4x + 4 – 6 y = 4x – 2 
PointSlope form

The most useful form of straightline equations. (y=mx+b)
* Find the equation of the straight line that has slope m = 4 and passes through the point (–1, –6). y = mx + b (–6) = (4)(–1) + b –6 = –4 + b –2 = b y = 4x – 2 
Slope Intercept Form

A line that has right angles to the horizon and is straight up and down. Slope is undefined.
x = 2.5 
Vertical Line

A line that is straight across and a constructive line, either drawn or imagined, which passes through the point of sight, and is the chief line in the projection upon which all verticals are fixed, and upon which all vanishing points are found.
y=2.5 
Horizontal Line
