Question

Write parametric equation of the line 9x+y=-1

Answer 1

Answencer:

Recall that a line has equation

y = mx + b

Suppose that one airplane moves along the line

y = 2x + 3

while the other airplane moves along the line

y = 3x - 2n:

Answer 2

x=t, y=-9t-1

Explanation:

9x+y=-1

9t+y=-1 Substitute t for x.

y=-9t-1 Solve for y by subtracting -9t from both sides.
