m=1/5
Step-by-step explanation:
Formula of the Slope
m = (y2 - y1)/ (x2 - x1)
(x1 , y1) = (20, 74)
(x2, y2) = (100, 90)
put values
m = (90 - 74) / (100 - 20)
m = 16 / 80 = 1/5

The friend will get 12 issues for $15.
A ratio indicates the number of times one number contains another.
Given that, the friend pays $1.50 per issue:
$1.5 = 1 issues
$1 = 1/1.5 issues
$15 = (1/1.5) × 15 issues
$15 = 10
Since the friend gets the first two issues free, he will get 10 + 2 =12 issues.
Hence, the friend will get 12 issues for $15.
