SOLUTION: 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 ?

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,

.

.
Yes, what you have is correct.
.
.
.
Now compare it to a line in slope-intercept form,

When ,

Comparing the terms, there is no x term so and .
Zero slope means horizontal line.
.
.
When ,

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.
