Final answer:
To find the parametric equations for the line passing through points P(-1, -1, 5) and Q(4, 6, -4), you can use the differences of the coordinates to determine the direction vector. Then, set up the parametric equations using the point-slope form and substituting the coordinates of point P.
Step-by-step explanation:
To find the parametric equations for the line passing through points P(-1, -1, 5) and Q(4, 6, -4), we can take the differences of the x, y, and z coordinates of the two points to determine the direction vector of the line. The direction vector is D = (4 - (-1), 6 - (-1), -4 - 5) = (5, 7, -9). Now, we can set up the parametric equations using the point-slope form and substituting the coordinates of point P:
x = -1 + 5t,
y = -1 + 7t,
z = 5 + (-9)t.
