Question

After 5 months, the number of subscribers to a newspaper was 5,730. After 7 months, the number of subscribers to the newspaper was 6,022. Which equation models the number of newspaper subscribers y after x months?

Answer 1

(5,5730) (7,6022)
slope = (6022 - 5730) / (7 - 5) = 292/2 = 146

y = mx + b
slope(m) = 146
(5,5730)...x = 5 and y = 5730
sub and find b, the y int
5730 = 146(5) + b
5730 = 730 + b
5730 - 730 = b
5000 = b

so ur equation is : y = 146x + 5000 <==
