Answer 1

Answer: D. (1,3), (2,8), (3,13), (4,18)

Step-by-step explanation:

We are given the function $y=5x-2$ and we want to find which table matches the x and y values.

In order to do this, we plug in the four x values :  1,2,3,4 and see what corresponding y-value we get.

By doing so, we can see which table of values is accurate.

When $x=1$:

$y=5(1)-2$ → $y=3$  Elimiate Table 1 (Answer option A)

When $x=2$:

$y=5(2)-2$→$y=8$ All other options can be elimated other than D

Let's still check the rest of the values to confirm our answer.

When $x=3$:

$y=5(3)-2$ →$y=13$ D is still good.

When $x=4$:

$y=5(4)-2$ → $y=18$ D is correct!

That's it!

Answer 2

Answer:

D

Step-by-step explanation:

if you take the values of x in D and replace them in the equation you will certainly note they are satisfying the equation
