25. A line passes through (2, -1) and (8, 4). Write an equation for the line in point-slope form. Rewrite the equation in standard form using integers.
y+1 = (x - 2); -5x + 6y = -16
5
y - 1 = 7(x - 2); -5x + 6y = 16
y - 2 = 7 (x + 1); -5x + 6y = 17
=
y + 1 = 7 (x + 2); -5x + 6y = -16

(least common multiples) the answer that i had in the 1st step was lcm of airline tickets sold=72. idk if that even matters but just in case. ! three co-workers are busy selling airline tickets over the phone. in an 8-hour day, charles can sell 8 airline tickets, ann can sell 9 airline tickets, and michelle can sell 6 airline tickets. step 2 of 2: what is the smallest number of 8-hour days needed for each of them to achieve the same number of sales? it takes charles . it takes . it takes .
