Find the range of values of `m` for which the line `y=m x+2` cuts the circle `x^2+y^2=1` at distinct or coincident points.

The range of values of m for which the line y = mx + 2 cuts the circle x^(2)+y^(2) = 1 at distinct or coincident points is :

The range of values of m for which the line y = mx+2 cuts the circle x^(2) +y^(2) =1 at distinct or coincident points is :

If the line y=mx-(m-1) cuts the circle x^(2)+y^(2)=4 at two real and distinct points then

For all values of m in R the line y-mx+m-1=0 cuts the circle x^(2)+y^(2)-2x-2y+1=0 at an angle

The straight-line y= mx+ c cuts the circle x^(2) + y^(2) = a^(2) in real points if :

The line x+2y+a=0 intersects the circle x^2+y^2-4=0 at two distinct points A and B. Another line 12x-6y-41=0 intersects the circle x^2+y^2-4x-2y+1=0 at two distincts points C and D. The value of 'a' so that the line x+2y+a=0 intersects the circle x^2+y^2-4=0 at two distinct points A and B is
