3x + 4y=1

y= mx+b ( slope-intercept )

Move 3x to the other side

Sign changes from +3x to -3x

3x-3x+4y= -3x+1

4y= -3x+1

divide both sides by 4

4y/4= y

-3/4x+1/4

y= -3/4x+1/4

y=mx + b

slope is also m

b is the y-intercept

Answer: slope= -3/4

\huge\boxed{-(3)/(4)}

This line is in standard form, or
ax+by=c. To find the slope of a line in standard form, simply find
-(a)/(b).

Substitute in the values.
\boxed{-(3)/(4)}
