What is the explicit formula for the sequence {3, 8, 13, 18, ...}? an = 3 – 5(n − 1)
O an = 3 +5,-1
An = 3 + 5(n − 1)
an = 3 + an-1

Isabel graphed the following system of equations. 2x – y = 6 y = -3x + 4 she came up with the solution (2,-2). what were the 3 steps she did to get that solution? (make sure they are in the correct order)
