Question 896424: the equation of a straightline passing through the point (2,-7) and parallel to x axis is
a)x=2 b)x=-7 c)y=-7 d)y=2
if the slope of the straight line ax+by+c=0 is -b/a, then the slope of the line parallel to it is

Slope is zero if parallel to the x-axis.
y value remains constant.



Using standard form, ax+by=c, you know that and this means .
