Answer
True.
Work Step by Step
general form of line is:
Ax + By +C = 0
In which A or B can be zero, but not at the same time.
slope intercept form derived from general form:
y = -$\frac{A}{B}$x +C
if line is vertical B = 0
X = -$\frac{C}{A}$
Same is possible if line is horizontal i.e A=0.
point slope form also reduces to general form only.
So, any line can expressed in general form.
