Find the equation of a line whose inclination is 60° and y-intercept is -4.

Write down the gradient and the intercept on the y-axis of the line 3y + 2x = 12.

If the line y = mx + c passes through the points (2, -4) and (-3, 1), determine the values of m and c.

If the points (1, 4), (3, -2) and (p, -5) lie on a line, find the value of p.
