Question

Determine which ordered pair is a solution of y equals 8x.
the answer choices are in the photo

Answer 1

(2,16)

To find which ordered paid out of the two given choices is the solution of y = 8x, we simply will try inserting the value of x & y given in the pairs into the equation (y=8x).

#1

Inserting the value of x as 1.5 & y as 10 ,

• => y = 8x
• => 10 = 8*(1.5)
• => 10 ≠ 12

Therefore,this ordered pair isn't the solution of the equation.

#2

Inserting the value of x as 2 & y as 16,

• => y = 8x
• => 16 = 8*2
• => 16 = 16

Therefore,this ordered pair is the solution of the given equation.

Answer 2

(2, 16)

Explanation:

We are given the equation y = 8x. There are two ordered pairs: (1.5, 10) and (2, 16). Ordered pairs are always written in the format (x, y). This means that in the first ordered pair, x = 1.5 and y = 10. In the second ordered pair x = 2, and y = 16. To see which ordered pair is a solution of the given equation, we must insert the x and y values into the equation.

Let's try ordered pair one first:

y = 8x ⇒ 10 = 8(1.5) ⇒ 10 = 12 ⇒ 10 does not equal 12, which means this ordered pair is not a solution of y equals 8x.

Now, let's try the second ordered pair:

y = 8x ⇒ 16 = 8(2) ⇒ 16 = 16 ⇒ 16 does in fact equal 16, which means this ordered pair is a solution of y equals 8x.
