Question

The slope is -2 and passes through (-1,6)?

Answer 1

and the equation is `y - 6 = -2 (x - -1)` or `y=-2 x + 4.`

Explanation:

Check: The slope is right so we check

`-2(-1) + 4 = 6 quad sqrt`

Answer 2

`y=-2x+4`

Explanation:

`y=mx+b rarr` Slope-intercept form of an equation (`m` is the slope and `b` is the y-intercept)

We know that the slope (`m`) is `-2`, so currently our equation is `y=-2x+b`

To get the y-intercept (`b`), put in `(-1, 6)` and solve:

`6=-2*-1+b`

`6=2+b`

`b=4`

The equation is `y=-2x+4`
