Question

Can someone help me? And possibley tell me how to solve this as well? I'm totally clueless haha

Answer 1

3

Explanation:

-2 * 3= -6

-1 * 3= -3

0 *3= 0

1 *3 = 3

2* 3 = 6

3 * 3 =9

Answer 2

? = 3

Explanation:

To find the value of ?, substitute one of the ordered pairs from the table [except (0, 0)] into the given formula and solve for ?.

Given formula:

`\sf y=\boxed{?} \:x`

Substitute x = 1 and y = 3 into the formula:

`\sf 3=\boxed{?} \:1`

To isolate ? divide both sides by 1:

`\implies \sf (3)/(1)=\frac{\boxed{?} \:1}{1}`

`\implies \sf 3=\boxed{?}`

Therefore, ? = 3:

`\implies \sf y=3x`

Check by inputting another value of x from the table into the found formula and comparing the calculated y-value:

`\sf x=-2 \implies y=3(-2)=-6 \quad \boxed{\sf correct}`

`\sf x=3 \implies y=3(3)=9 \quad \boxed{\sf correct}`
