By changing the equation to slope intercept form, which would be y=-2/7x-40/7

Explanation:

The general way to graph a line like this is to get it into slope intercept form which is y=mx+b

So generally, just solve for y.

2x+7y=-40
7y=-2x-40
y=-2/7x-40/7

You may put it into decimals if you wish but it's not really necessary.

From this equation we can see that the slope is -2/7 and the y intercept is -40/7.

The graph ends up looking like:
graph{y=-2/7x-40/7 [-29.01, 28.72, -11.67, 17.18]}
