You can put this solution on YOUR website! Coordinate-system/249560 (2009-12-14 01:17:09): Give the equation of the line that contains (-9, 8) and (-9, -7)
This one should be fairly easy.
We know that if the x or y component is the exact same for any 2 points on a straight line, then that line must either be a horizontal or vertical line. There are no other possibilities.
In this example, we can see that both points share -9 as their x components.
Thus, the equation for this line is simply:
x=-9 which is a vertical line that intersects the point (-9,0) on the x-axis (the line shown in blue in the drawing),
and that will hold true for EVERY real value of y.
