Question

What is the slope of the graph of 8x – 4y = 11?
a.1/2
b.-1/2
c.-2
d.2

Answer 1

The standard form of an equation which describes a line is
\[y=mx+b\]wherre m is the slope of the line
to find the slope bring your equation to the standar form:
\[-4y=11-8x=>4y=8x-11=>y=\frac{ 8x-11 }{ 4 }=>y=\frac{ 8x }{ 4 }-\frac{ 11 }{4}\]
which is equal to:
\[y=2x-\frac{ 11 }{ 4}\]
