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

Use the point-slope form to write an equation of the line with the given slope and point. Then write the equation in slope-intercept form. slope 4 , passes through \( (4,6) \)

Factorise coumpletely. \( 21 a^{2}+28 a^{b} \)
