Question

How do you graph using slope and intercept of `2x+7y= - 40`?

Answer 1

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]}
