EXAMPLE 3 Parametric equations of lines
a. Consider the parametric equations x = -2 + 3t, y = 4 – 6t, for – 0 <t< ∞,
which describe a line. Find the slope-intercept form of the line.
b. Find two pairs of parametric equations for the line with slope – that passes through the
point (2, 1).
c. Find parametric equations for the line segment starting at P(4,7) and ending at
Q(2, –3).
