Question 958379: When the equation of a line is written in general form, Describe the Slope of the line when A=0 or
and B=0 ?
I tries:
When A=0
y= -C/B
When B=0
x= -C/A
correct ?

I assume the original equation is,
Ax%2BBy%2BC=0

Yes, what you have is correct.

.
Now compare it to a line in slope-intercept form,
y=mx%2Bb
When A=0,
y=-C%2FB
Comparing the terms, there is no x term so m=0 and b=-C%2FB.
Zero slope means horizontal line.

.
When B=0,
x=-C%2FA
When you compare to the standard case, it's not possible to compare.
In this case, it is a vertical line and doesn't have a slope-intercept form because the slope is undefined.
