How does slope intercept form differ from standard form?

Slope intercept form:
y = mx + c

where m is the slope and c the y-intercept

so this form shows you the gradient and the intercept of a line only.

Whereas, the standard from:
ax + bx + c = 0

where a, b and c are just constants.
This form doesn't show you gradient nor intercept,
on the other hand its useful when applying some formulae such as,

the perpendicular distance between a point and a line:

Distance = |(ax + by + c)/sqrt(a^2 + b^2)|
