Write equation in standard formate

y + 1 = 4/5(x-3)

Y=4x/5 - 17/5

this is the correct answer and basically just knowing how it would look if you would to plot these points on a graph

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 *_*
