Answer & Step-by-step explanation:

The formula is given in the middle. You are supposed to insert the value of x into this formula to find the value of y (like in the first given example):

x=-2\\y=2(-2)+5\\y=-4+5\\y=1

------

x=-1\\y=2(-1)+5\\y=-2+5\\y=3

------

x=0\\y=2(0)+5\\y=0+5\\y=5

------

x=1\\y=2(1)+5\\y=2+5\\y=7

------

x=2\\y=2(2)+5\\y=4+5\\y=9
