The slope of the perpendicular line is the negative reciprocal of that of the given line, so is
-1/(3/5) = -5/3
Then the point-slope equation of the perpendicular line can be written as
y = (-5/3)(x -15) -5
y = (-5/3)x +20
The y-intercept of the perpendicular line is y=20.
-1/(3/5) = -5/3
Then the point-slope equation of the perpendicular line can be written as
y = (-5/3)(x -15) -5
y = (-5/3)x +20
The y-intercept of the perpendicular line is y=20.
Answer:
P(6, 1)
Step-by-step explanation:
Point P is the weighted average of the end point coordinates. The weights are the reverse of the order of the segment lengths:
P = (2A +3B)/(2+3)
P = (2(-3, -2) +3(12, 3))/5 = (-6+36, -4+9)/5
P = (6, 1)
