On plotting the points (−3,−2),(−2,−2),(0,−2),(1,−2) amd (3,−2), we get a line that:
ax2+2hxy+by2=0 always represents a pair of straight lines passing through the origin. If
Column 1 Column 2
a. h2>ab 1. Lines are coincident
b. h2=ab 2. Lines are real and distinct
c. h2<ab 3. Lines are imaginary with real point of intersection i.e. (0,0)
