Answer:

y= 8x+1 (0,1) y=6x+3 (0,1)

= 8×0+1 =6×0+3

y = 1 =3

Step-by-step explanation:

= 8×1+1 (1,9) =6×1+3 (1,9)

y=9 =9

=8×4+1 (4,14) =6×4+3 (4,14)

y=33 =27

=8×2+1(2,4) =6×2+1 (2,4)

y=17 =13

So first, we multiply out the brackets.
-15x - 18 + 2 = 17 + 16x -1
Then, bring all the terms onto one side so you can solve.
-15x-18+2-17-16x+1=0
Then, we simplify this.
-31x-32=0
Then, isolate x
-31x=32
x=32/-31 or -1.03 (nearest hundredth )
