Answer:
Step-by-step explanation:
y = -2x + 5
x = -4 ; y = -2*-4 +5 = 8+5 = 13
x = -3; y = -2*-3 + 5 = 6+5 =11
x = -2; y = -2*-2 + 5 = 4+5 = 9
x= -1; y = -2*-1 + 5 = 2+5 = 7
x = 0; y= -2*0 + 5 = 0+5 = 5
x= 1; y = -2*1 + 5 = -2 +5 = 3
x= 2; y = -2*2 + 5 = -4+5 =1
x=3; y= -2*3 + 5 = -6+5 = -1
x = 4; y = -2*4 + 5= -8 + 5 = -3
It is D. 320 because if you add 80 and 40 togeter you get 120 then 320
