Graph the line that passes through the points (-9,5) and (-9,-5) and determine the equation of the line.

x=-9

Step-by-step explanation:

M(slope)=y2-y1/x2-x1

m=-5-5/-9+9

m= -10/0

This means the slope is undefined. Whenever the slope is undefined, the line is vertical and is passing through the x-axis and parallel to the y-axis. Take the given coordinate (-9,5) and all you do is put x= -9. That's the equation of the line.

answer: a.   one is a factor of every whole number since every number is divisible by itself.

use this formula:

p(a\b) = p(a and b)/p(b).
