The cost of oranges in a grocery store is directly proportional to the number of oranges purchased. Jerri paid $2.52 for 6 oranges. If p represents the cost, in dollars and n represents the number of oranges purchased, which equation best represents this relationship?

(a) (8%) compute the probability of an even integer among the 100 integers 1! , 2! , 3! , until 100! (here n! is n factorial or n*(n-1)*(n-2) *… 1) (b) (16%) compute the probability of an even integer among the 100 integers: 1, 1+2, 1+2+3, 1+2+3+4, …., 1+2+3+… + 99, and 1+2+3+… + 100

Give all possible names for the line shown. calculation tip: lines can be written with either point first.

[10 points, algebra 2]according to my answer key the restrictions are -1 and 4. but why not positive 1?
