Choose the equation below that represents the line passing through the point (2, -4) with a slope of 1/2. 
A) y = 1/2 x + 5 
B) y = 1/2 x - 3 
C) y = 1/2 x - 5 
D) y = 1/2 x + 3

we only need to put the values and find the equation

\(y=\frac{1}{2}*x+5\)

\(-4=\frac{1}{2}*2+5\)

\(-4=6\)

False

\(y=\frac{}{}*x-3\)

\(y=\frac{1}{2}*x-3\)

\(-4=\frac{1}{2}*2-3\)

\(-4=-2\)

False

\(y=\frac{1}{2}*x-5\)

\(-4=\frac{1}{2}*2-5\)

\(-4=-4\)

True

\(y=\frac{1}{2}*x+3\)

\(-4=\frac{1}{2}*2+3\)

\(-4=4\)

False

\(\boxed{\boxed{\therefore~the~equation~that~represents~the~line~is~~C}}\)
