Hi,
*Note: The slope of a line and slope of a line perpendicular to it: are negative reciprocals
.
First find the slope of the line given:
Put it into a slope-intercept form of a line: y = m*x = b
(m being the slope ad b the y-inteccept)
.
2x � 5y =3
.
Solve for y
� 5*y = -2*x+ 3

m = 2/5
The slope of the line perpendicular to it is: m = -5/2
