Which table shows y as a function of x

Option 1 \table[[x,y],[-13,-2],[-13,0],[-13,5],[-13,7]]

Option 2 \table[[x,y],[1,4],[3,4],[7,4],[12,4]]

Option 3\table[[x,y],[-6,3],[-1,-1],[-1,5],[10,-9]]

Option 4\table[[x,y],[-9,-7],[-2,-5],[0,0],[0,6]]

In word problems like this, the hardest part is translating the words into math.
First identify the quantities involved.
Let x be “a number”

Next Translate the words.
Translate “three times a number” into “3x”
Translate “the difference between 3x and twelve” into ”3x-12”
Translate “is equal to eight more than x” into “ =8+x”
now string them together:

3x-12 = 8+x
