Question

The line y = -4x -20 meets the x - axis at the point P. Write out the coordinates of P.

Answer 1

P (- 5, 0 )

Explanation:

To find where the line meets the x- axis, let y = 0 , that is

- 4x - 20 = 0 ( add 20 to both sides )

- 4x = 20 ( divide both sides by - 4 )

x = - 5

The coordinates of P are (- 5, 0 )
