I am currently studying the applications unit in higher maths and I am on the circle topic. I am stuck on this question: Determine whether the line with equation 3y-5x=11 is a chord, tangent, or does not touch the circle with equation x2+y2-14x-8y+31=0. I am not sure how to substitute the equation into the circle equation as if you rearrange it, it comes out as fractions if I am right. Can anyone help me with this? Thank you in advance!
