Solution
We know that the equation of the line passing through the point (x0, x0),
Whose slope is m, (y − y0) = m(x − x0),
Thus, the equation of the line passing through the point (−4, 3), whose slope is `1/2`, is:
(y – 3) = `1/2` (x + 4)
2(y – 3) = x + 4
2y – 6 = x + 4
0 = x – 2y + 4 + 6
∴ x – 2y + 10 = 0
Hence, the equation of the line is x – 2y + 10 = 0.
