(a) Gradient of the line
-$\frac{3}{5}$ + 3y = 6 is
-3x + 15y = 30;
15y = 3x + 30
5y = x + 10;
y = $\frac{x}{5}$ + $\frac{10}{5}$
y = $\frac{x}{5}$ + 2; gradient is $\frac{1}{5}$
(b) Equation of the
perpendicular line through
(1,2) is
$m_2 = -5;$ $\frac{y-2}{x-1}$ = -5
y-2 = -5x + 5
y = -5x + 5 + 2,
y = -5x + 7
