Answer:
2n
Step-by-step explanation:
(3,1) y= x -2, <span> when x = 3, y = 3 -2 = 1 ....YES
</span>(1,3) y= x -2 , when x = 1, y = 1 -2 = -1 ....NO
(-1,3) y= x -2 , when x = -1, y = -1 -2 = -3 ....NO
(3,-1) y= x -2 , when x = 3, y = 3 -2 = 1 ....NO
answer is
<span>A-(3,1)</span>
Answer:
d=-1
Step-by-step explanation:
10(1+3d)= -20

divide both sides by 3
d=-1
