Write the equation for a line in slope-intercept form that has a y-intercept of (0,5) and a slope of 7. y = 5x +7
y=x+5/7
y=7x+5
y=7/5x
y=x+7/5
y=5/7x

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 *_*
