the equation y = 2.1x represents the relationship between x, the number of tickets, and y, the price. which ordered pairs represent a number of tickets and the corresponding price in the given equation? choose all that apply. (3,6.3) (6.3,3) (2.1,10.5) (7,14.7) (10.5,2.1) (14.7,7)

Answer

Explanation:

Step1: Recall the equation

The equation is $y = 2.1x$.

Step2: Check the ordered - pair $(3,6.3)$

Substitute $x = 3$ into the equation: $y=2.1\times3 = 6.3$. So, $(3,6.3)$ is a valid ordered - pair.

Step3: Check the ordered - pair $(6.3,3)$

Substitute $x = 6.3$ into the equation: $y=2.1\times6.3=13.23\neq3$. So, $(6.3,3)$ is not a valid ordered - pair.

Step4: Check the ordered - pair $(2.1,10.5)$

Substitute $x = 2.1$ into the equation: $y=2.1\times2.1 = 4.41\neq10.5$. So, $(2.1,10.5)$ is not a valid ordered - pair.

Step5: Check the ordered - pair $(7,14.7)$

Substitute $x = 7$ into the equation: $y=2.1\times7=14.7$. So, $(7,14.7)$ is a valid ordered - pair.

Step6: Check the ordered - pair $(10.5,2.1)$

Substitute $x = 10.5$ into the equation: $y=2.1\times10.5 = 22.05\neq2.1$. So, $(10.5,2.1)$ is not a valid ordered - pair.

Step7: Check the ordered - pair $(14.7,7)$

Substitute $x = 14.7$ into the equation: $y=2.1\times14.7=30.87\neq7$. So, $(14.7,7)$ is not a valid ordered - pair.

Answer:

$(3,6.3),(7,14.7)$
