Question

Which equation has a slope of −2 and passes through the point (1, −6)?

Answer 1

`y=-2x-4`

Explanation:

You can solve this equation using the point slope formula, which is as following:

`y-y_(1) =m(x-x_(1) )`

When using this equation,
`y_(1)` is equal to the y value in the known point,
`x_(1)` is equal to the x value in the known point, and m is equal to the slope. With this knowledge, this is how you would solve this problem.

`y-y_(1) =m(x-x_(1))\\ \\y+6=-2x+2\\\\y=-2x-4`
