Edward works at a grocery store. he kept track of the number of coupons redeemed by the last 20 shoppers. the center of the dot plot was 1. no one redeemed 4 coupons. most people did not redeem any coupons. which dot plot displays this information correctly

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
