Question #f5184

Answer 1

`y = 4x - 25`

Explanation:

The slope-intercept form follows this general format:
`y = mx + b`
such that,
`m = "slope"`
`b = "y-intercept"`

In this case, since we know that the slope is `m = 4` we can use it in the general format.
`y = 4x + b`

In order to determine `b` or the y-intercept, we can substitute the coordinates given above, where the line passes through.

`(6, -1)`
`y = 4x + b`
`-1 = 4 (6) + b`
`-1 = 24 + b`
`b = -25`

So we know that the equation of the line is `y = 4x - 25`
