1. Slope-Intercept form:
Y=mx+b
2. Point-slope form:
The equation of a line passing through a point (x1, y1) with slope m
y − y1 = m(x − x1)
Genreral Form of Straight line is given by:
Ax+By+C=0
Conic Section:
If we slice the double cone by a plane just touching one edge of the double cone, the intersection is a straight line, as shown above.
