(a) The equation of the line through (0,0) which is perpendicular to y = x is y = -x
1.IT SATISFIES 0,0...
2.SLOPE=-1/1=-1..OK....TRUE
(b) The line 2x � y = -1 goes through the point (-2,-3)
SUBSTITUTING
LHS=2*-2-(-3)=-4+3=-1=RHS....TRUE

a) TRUE. Slopes are negative reciprical of the other.
b) TRUE. 2*-2-(-3)=1 or 2-2+3=1 or 4-3=1 or 1-1
