we only need to put the values and find the equation

[tex]y=\frac{1}{2}*x+5[/tex]

[tex]-4=\frac{1}{2}*2+5[/tex]

[tex]-4=6[/tex]

False

[tex]y=\frac{}{}*x-3[/tex]

[tex]y=\frac{1}{2}*x-3[/tex]

[tex]-4=\frac{1}{2}*2-3[/tex]

[tex]-4=-2[/tex]

False

[tex]y=\frac{1}{2}*x-5[/tex]

[tex]-4=\frac{1}{2}*2-5[/tex]

[tex]-4=-4[/tex]

True

[tex]y=\frac{1}{2}*x+3[/tex]

[tex]-4=\frac{1}{2}*2+3[/tex]

[tex]-4=4[/tex]

False

[tex]\boxed{\boxed{\therefore~the~equation~that~represents~the~line~is~~C}}[/tex]
