**d) **$\displaystyle 3x+5y=6$

Make y the subject of the equation.

$ \displaystyle 2y=-3x+6$

$ \displaystyle y=\frac{{-3}}{2}x+\frac{6}{2}$

$ \displaystyle y=\frac{{-3}}{2}x+3$

The coefficient of x is $ \displaystyle -\frac{3}{2}$ so the gradient is m=-3/2

The constant term is c=3 so y intersect is (0,3)
