See explanation.

Explanation:

For an atom to be sp-hybridized it means that its $s$ $s$ and $p$ $p$ orbitals will combine and form new orbitals in order for the molecular geometry around this atom to be linear and the bond angle equals $180^{\circ}$ $180^@$ .

For example, carbon atoms in ethyne ( $H C \equiv C H$ $HC-=CH$ ) are sp-hybridized.

The one $s$ $s$ orbital combine with one $p_{x}$ $p_x$ orbital to give two $s p$ $sp$ orbitals and the two $p_{y}$ $p_y$ and $p_{z}$ $p_z$ orbitals will be used to form the two $π$ $pi$ bonds.

Therefore, for a carbon atom in ethyne:

Two $s p$ $sp$ orbitals to form two $σ$ $sigma$ bonds. The $H - C$ $H-C$ and $C - C$ $C-C$ bonds.

The $p_{y}$ $p_y$ and $p_{z}$ $p_z$ to form two $π$ $pi$ bonds $C \equiv C$ $C-=C$ .
