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.
