Answer:

(4,18)

Step-by-step explanation:

We can just pluck the x values into the equation: y = 5x -1 to see if the y values fit.

1. y = 5(4) - 1

    = 20 - 1

    = 19 (Nope, 18 is not 19)

2. y = 5(3) - 1

     = 15 - 1

     = 14 (Yep, same as option)

3. y = 5(0) - 1

     = 0-1

     = -1 (Yep, same as option)

4. y = 5(2) - 1

     = 10 - 1

     = 9 (Yep, same as option)

B :+7=y
C 3x+1=y
D) 4.1 - 1=y

Answers

9514 1404 393

Answer:

  C  3x +1 = y

Step-by-step explanation:

x-values increase by 1 from row to row.

y-values increase by 3 from row to row.

The slope of the linear function is the ratio of the y-increase to the x-increase:

  m = ∆y/∆x = 3/1 = 3

The only offered choice with an x-coefficient of 3 is ...

  C  3x +1 = y

__

If you check this against the table entries, you find it fits.

  3(1) +1 = 4

  3(2) +1 = 7

and so on.
