Which of the following represents a line parallel to x-axis?
x + 3 = 0
x + y = 7
y + 2 = 2y - 5
5x + 3 = 4
2y - y = 2 + 5
y = 7
Since for all the values of x, value of y = 7, therefore, the line will be parallel to x-axis.
Find the slope of the line which is parallel to :
(i) x + 2y + 3 = 0
(ii) x2−y3−1=0
