If `theta` is the angle between `y=2x+3, y=x+1`, the value of `tan theta=`

Two tangents are drawn from the point (-2,-1) to the parabola y^(2)=4x .If theta is the angle between these tangents,then the value of tan theta is

If (theta) is an acute angle between the lines y=2x+3,y=x+1 then the value of tan theta=

If theta is the angle between the curves y=x^2,x=y^2 at (1,1), than tan theta =

If the regrassion coefficient of Y on X is 1.6 that of X on Y is 0.4 , and theta be the angle between two regression lines , find the value of tan theta

If theta is the angle between y=x^(2) and 6y=7-x^(3) at.(a,a) Find theta

If theta is the angle between the curves xy = 2 and x^(2)+4y = 0 then tan theta =

Consider the equation of a pair of straight lines as 2x^(2)-10xy+12y^(2)+5x-16y-3=0 . The angles between the lines is theta . Then the value of tan theta is
