Rewrite `y - 3 = 3 (x+1)` in slope intercept form: distribute 3 and add three to both sides we get:
`y = (3x + 3) + 3 = 3x + 6`
`y = 3x + 6` Slope intercept form. Y-intercept is (0, 6) and slope is 3.
To rewrite this equation in standard form (ax + by = c), subtract y from each side, and subtract 6 from each side, we'd get: `3x - y = -6.`
x-intercept, we let y = 0, so `3x = -6, so x = -2`
x-intercept = `(-2, 0)`
The line perpendicular to this line will have the opposite reciprocal slope. The original equation has a slope of 3 as defined earlier, therefore the `_|_` line has a slope of `-1/3.`
Using point slope form`y-y_(1)=m(x -x_(1))` with slope of `-1/3` and containing point (5,1) we have the equation:
`y - 1 = -1/3 (x - 5)`
` `Now place in standard form by multiplying both sides by -3 to get:
`-3(y - 1) = x - 5` Distribute -3 to get:
`-3y + 3 = x - 5` Rearrange to ax + by = c, to get:
`x + 3y = 8`
