The slope for y = -4x + 14 is m =- 4
The slope for y - 3 = 1/4(x+2) is m = 1/4
In this case m = -4 and m = 1/4 are opposite reciprocal slopes
so these lines are perpendicular

the first has a slope of -4
the 2nd has a slope of 1/4
those slopes are negative inverses, so the lines are perpendicular
-4 is the negative inverse of 1/4, just change the sign and flip it upside down
