How to find the equation of a line if the gradient is undefined?

And when gradient is not given like in this question:
(5,-3), 2x=3

Please help!

please refer the year from which u took this question or the complete question if took from a book .. I ust want sumthing more to understand what is the question about

thank u in advance

t can take any value between the value of 0 and 2.5(bt not including 2.5). Since the denominator can't b negative or zero, bcoz radius is always positive

How to find the equation of a line if the gradient is undefined?

And when gradient is not given like in this question:
(5,-3), 2x=3

Please help!

If the gradient is undefined then the line will be parallel to the y-axis... therfore u will only need to write the equation parallel to y-axis....ie x=-2, x=5, x=2.5 , etc

plz br precise and need it urgently plz

Just insert the values of x=a ( cos t)^3 and y= a ( sin t)^3 and for the gradient insert the value of dy/dx
