got y=-3x+25 for a
the only unknwon in circle is radius
i subbed in y=-3x+25 to eqwuatin for cicrcle i have (the lhs)
i think i can only solve it if the discriminant is 0
is that valid?
im quite confident with
10x^2-140x+500-r^2=0
Same
then i get r=root10 if it is valid that discrim = 0
It’s just 1/3 x = -3x+25
Lol
