Question

Describe a linear equation in the form Ax + By = C for each condition.

a. A = 0

b. B = 0

c. C = 0

Answer 1

a) when A =0 the line is parallel to the X-axis and passes by the point (0,C/B)
b) when B=0 the line is parallel to the Y-axis and passes by the point (C/A ,0 )
c) when C=0 the line passes by the origin and the slope is (-A/B)
