Find a point-slope form of the line that passes through the point \((0, b)\) with slope \(m\text{.}\)
2.
Find a point-slope form of the line that passes through the point \((a, 0)\) with slope \(m\text{.}\)
3.
Two lines are parallel if they have the same slope. Find the point-slope form of the line that passes through the point \((2, -1)\) that is parallel to the line \(y = 2x - 3\text{.}\)
4.
Two lines are parallel if they have the same slope. Find the point-slope form of the line that passes through the point \((-1, -3)\) that is parallel to the line \(y - 2 = \frac{4}{3} (x + 1)\text{.}\)
