a). The equation x^2+y^2-2<0
b). The slope of a straight line can't be equal to zero.
c)If /a/=/b/, then a=b

Answer 1

(a) is true only ic some cases
(b) is false slope can be equal to zero
(c)this is true when a/b are positive

Answer 2

(c) can also be true when a and b are both negative.

Answer 3

a). solve the equation x^2+y^2-2<0

Answer 4

x^2+y^2-2<0 is the interior of a circle of radius √2
