Постройте на координатной плоскости прямую, заданную уравнением ax + by + c = 0, при следующих значениях коэффициентов a, b и c:
а) a = 0, b = 2, c = −6;
б) a = −1, b = 0, c = −2;
в) a = 0, b = −2, c = −4;
г) a = 5, b = 0, c = −5.
a = 0, b = 2, c = −6.
2y − 6 = 0
y − 3 = 0
y = 3
a = −1, b = 0, c = −2.
−x − 2 = 0
x = −2
a = 0, b = −2, c = −4.
−2y − 4 = 0
y + 2 = 0
y = −2
a = 5, b = 0, c = −5.
5x − 5 = 0
x − 1 = 0
