Please see the graph.

Work Step by Step

$2x-7y=14$ Let $x=0$ $2x-7y=14$ $2*0-7y=14$ $-7y=14$ $-7y/-7=14/-7$ $y=-2$ Let $y=0$ $2x-7y=14$ $2x-7*0=14$ $2x=14$ $2x/2=14/2$ $x=7$ Let $x=14$ $2x-7y=14$ $2*14-7y=14$ $28-7y=14$ $14-7y=0$ $14=7y$ $14/7=7y/7$ $2=y$ Three points on the line are $(0,-2), (7,0),$ and $(14,2)$.
