Question

plzz solve this question how to get ans x+1/2. and what has happend to y+2 . it is based on point slope form?

Answer 1

The equation is as :

(y+2) = ∞ (x+½)

Divide by (x+½) on the both sides

(y+2)/(x+½) = ∞ (x+½)/(x+½)

(y+2)/(x+½) = ∞

Now,
since ∞ can be written as (1/0)
then the above equation can be written as ;

(y+2)/(x+½) = 1/0

0 × (y+2) = 1 × (x+½)

0 = x+½

x = -1/2

Hope you got what happened with y+2
