What is the slope of the line described by the equation 2x-4y+3=0

Standard form of a line is
Ax+By=C

slope-intercept form of a line is
y=mx+b
where m is the slope and b is the intercept

if you convert standard form intoslope intercept

Ax+By=C
By=-Ax+C
y= -A/B *x +C/B
slope --        m= -A/B
y-intercept --b= C/B
