Use the function rule to complete the table -10x+y=4 table x= -2,-1, 0, 1, 2

Question

I think the answers might be -2=-16/ -1=-6
0,4/ 1,14/ 2,44

Please tell if I’m right.

Answer 1

arrange the equation -10x+y=4 to
y = 10x + 4 , that way you can do your calculations in your head,
just take the x, multiply by it by 10, then add 4

so when x = -2, y = (-10)(-2)+4 = 20+4 = 24
when x = -1, y = 10+4 = 14
continue

you might notice that as x increases by 1, the y decreases by 10
