For finding the equation of the line witch is perpendicular to y=2x
Given line y= 2x , here slope is 2
Required slope is= -½
Because m(2)=-1/m(1)
Line can be written as for slope -½
Y= -½ x+c ……(1)
This line equation passing through the point (-3,8.5) substitute x=-3and y= 8.5 into equation (1)
8.5 =-½*-3 +c
C= 8.5-3/2
C=7
Putting value c in equation (1)
Y= -½x +7 is the equation fr the line that is perpendicular to y=2x and passes through the point (-3,8.5).
