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
Use the function rule to complete the table -10x+y=4 table x= -2,-1, 0, 1, 2
I think the answers might be -2=-16/ -1=-6
0,4/ 1,14/ 2,44
Please tell if I’m right.
