Answer:
1. in classical geometry, a radius of a circle or sphere is any of the line segments from it's center to its perimeter, and in more modern usage, it is also their length.
2. standard from for linear equation in two variables is AX + BY = C
A = integer
X = x intercept
B = integer
Y = y intercept
C = integer
this is the standard equation
3. Ax + By + C = O. A or B can be zero, but not both at the same time. the general form is not always the most useful form, and you may prefer to use. the slope -intercept form of the equation of a straight line: y = mx + b
