If the line is perpendicular, then as a rule the gradient of the perpendicular line will be the negative inverse of the gradient of the line given.
Therefore the gradient of the perpendicular line would be 1/2
so now just substitute in the equation of a line (y=mx+c) where y and x are given by -3 and 9, and your new m=1/2
Hope this helps

I believe the correct answer from the choices listed above is the second option. If an oxygen atom has 8 protons and 10 neutrons in its nucleus, then its atomic number would be 8. The atomic number is <span>the number of protons in the nucleus of an atom. Hope this answers the question.</span>
