What is the unknown? \( 8 \times(2 \times 3)=(? \times 2) \times 3 \) A. 6 B. 8 C. 16 D. 48

Find the \( x \) - and \( y \)-intercepts of the graph of the equation. Do not graph the line. \[ \begin{array}{l}7 x+5 y=35 \\ x \text {-intercept } \quad(x, y)=(\square) \\ y \text {-intercept } \quad(x, y)=(\square)\end{array} \]

1) \( y=6 x \)
