9. Find the equation of the line with given gradient and y-intercept. Give your answer in the form ax + by + c = 0. Gradient: -2/3 y-intercept: (0,6)​

Answer to your question: a. the fundamental theorem of algebra tells you that the equation will have two complex roots since the degree of the polynomial is 2. the roots are ​ x=1±i7√2 .number of roots=degree of polynomialhere, degree of polynomial is 2 so number of roots will be 2.hope it *_*
