the table shows the temperature (y) at different altitudes (x). this is a linear relationship. use the equation y = 0.004x + 69 to determine the temperature at an altitude of 5,000 feet

The linear equation is: y=ax+b

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 *_*
