3 * 3 =9
Answer:
? = 3
Step-by-step 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:
[tex]\sf y=\boxed{?} \:x[/tex]
Substitute x = 1 and y = 3 into the formula:
[tex]\sf 3=\boxed{?} \:1[/tex]
To isolate ? divide both sides by 1:
[tex]\implies \sf \dfrac{3}{1}=\dfrac{\boxed{?} \:1}{1}[/tex]
[tex]\implies \sf 3=\boxed{?}[/tex]
Therefore, ? = 3:
[tex]\implies \sf y=3x[/tex]
Check by inputting another value of x from the table into the found formula and comparing the calculated y-value:
[tex]\sf x=-2 \implies y=3(-2)=-6 \quad \boxed{\sf correct}[/tex]
[tex]\sf x=3 \implies y=3(3)=9 \quad \boxed{\sf correct}[/tex]
