If we can express $4x-3y=27$
in the slope-intercept form: $y = mx+b$
we will be able to read the slope and y-intercept directly from the equation.

$4x-3y=27$

$rarr -3y = -4x+27$

$rarr y = (4/3)x + (-9)$

The slope is $(4/3)$
and the y-intercept is $(-9)$

I would write it in Slope-Intercept form to "read" these information directly.

To do that simply isolate $y$ on one side as:

$y=4/3x-9$

So:
Slope= $4/3$
y-intercept= $-9$

How do you find the slope and y intercept for 4x - 3y = 274x - 3y = 27?
