Write an equation for the line described. Give the answer in standard form. through \( (1,9), m=-8 \)

1) \( \begin{array}{l}y=4 x-17 \\ y=x-5\end{array} \)

1) \( y \div 2+x ; \) use \( x=1 \), and \( y=2 \)

5) \( m+p \div 5 ; \) use \( m=1 \), and \( p=5 \)

Determinar si es falso o verdadero: Sean \( H_{1} \) y \( H_{2} \) subespacios de un espacio vectorial \( V \). Entonces \( H_{1} \cap H_{2} \) es un subespacio de \( V \).

A bus driver has a tax credit of \( € 60 \) a week and pays income tax on all his wages standard rate of \( 20 \% \). If he pays \( € 140 \) in income tax for the week, find his gross weekly wage.
