Best Answer

The y intercept will be where the x-coordinate is zero, so set x=0 in the equation and you have: 0 + y = -9, or y = -9. Coordinate (0,-9)

Q: What are the coordinates of the y-intercept in the graph of the equation x plus y equals negative 9?

The coordinates of every one of the infinitely many points on the line defined by the equation is a solution.

The coordinates of the x intercept for the equation y equals x plus 1 is (x=-1, y=0).

-4x + 9y = 0 is the equation of a line in the Cartesian plane and the coordinates of any of the infinite number of points on that line will satisfy the equation.
