a line on a graph shows a proportional relationship between the hours worked, x, and the total pay y. two points on the graph are located at (6, 58.50) and (9, 87.75) .
what is the unit rate for the pay per hour?
$4.88 per hour
$9.75 per hour
$19.50 per hour
$29.25 per hour

Unit rate can be found by calculating rate of change. $58.50/6 is $9.75 per hour.

Hnmmmn not sure

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 *_*
