We'll recall the fact that the product of the slopes of
two perpendicular lines is -1.
Therefore, we'll re-write
the given equation in the slope intercept form:
y = mx + n,
where m is the slope and n is the y intercept.
3x - 2y =
5
We'll isolate -2y to the left
side:
-2y = -3x + 5
We'll
divide by -2:
y = 3x/2 -
5/2
Comapring the equations, we'll get the slope m1 =
3/2
The slope of the perpendicular line is determined from
relation:
m1*m2 = -1
m2 =
-1/m1
m2 = -1/(3/2)
m2 =
-2/3
We'll write the point slope form of the equation of
the line:
y - y2 = m2*(x - x2), where x2 = 5, y2 = -2 and
m2 = -2/3
y - (-2) = (-2/3)*(x -
5)
y + 2 = -2x/3 + 10/3
y =
-2x/3 + 10/3 - 2
y = -2x/3 +
4/3
The equation of the line, which is
passing through the point (5,-2) and it is perpendicular to the line 3x - 2y = 5, is: y
= -2x/3 + 4/3.
