Question

The circle x²+y²+4x-7y+12=0,cuts an intercept on y axis equal to

Answer 1

Answer:

Step-by-step explanation:

Let x = 0 which is the equation of y- axis. We get y^2 - 7y + 12 = 0 

=> y^2 - 4y - 3y + 12 = 0

=> y(y - 4) - 3(y -4) = 0

=> (y-4)(y-3) = 0 

=> y = 3 or 4.

So the intercept has endpoints (0,3) and (0,4) which makes it 1 unit long
