Question

Use the function rule to complete the table
-10x + y = 4

Answer 1

Given the function:

`-10x+y=4`

For x = -2

then;

-10(-2)+y= 4

⇒20+y = 4

Subtract 20 from both sides we have;

y = -16

Similarly for:

For x = -1

then;

-10(-1)+y= 4

⇒10+y = 4

Subtract 10 from both sides we have;

y = -6

For x = 0

then;

-10(0)+y= 4

⇒0+y = 4

y = 4

For x = 1

then;

-10(1)+y= 4

⇒-10+y = 4

Add 10 from both sides we have;

y = 14

For x = 2

then;

-10(2)+y= 4

⇒-20+y = 4

Add 20 from both sides we have;

y = 24

x y

-2 -16

-1 -6

0 4

1 14

2 24
