General equation of a line in the plane ax by
c a or b not zero. Vertical line
Horizontal line Problem Suppose ax by c
is the equation of a nonvertical line. What is
the slope of the line in terms of a, b,
c? Problem When does the line ax by c
have an x-intercept And what is it in terms of a,
b, and c?

Many times the relationship between variables is
linear. Problem Find the linear equation
relating fahrenheit temp F to centigrade temp C.
Use the facts that C0 when F 32 and C100 when
F 212.
