You need to know how many miles and how many hours
Answer:
C. 3x + 2y = 5 and 2y = 6 - 3x & D. 3x = 2 − 4y and 4y = 7 − 3x , have no solution! (:
To draw the graph of a linear equation , two points are more than enough to draw a line.
But sometimes we may commit a mistake and then if we draw the line, everything appears good. As two points shall always define a line irrespective of the points are correct or not.
So in order to make sure that the points we obtained are correct , we take a third point to ensure that the two points calculated earlier are correct and all points lie on the same line. If they don't we have committed some mistake.
Option A) is the right answer
