Question

HURRYYY PLEASE...

The ordered pairs in the table lie in the graph of the linear function whose equation is
y = 3x + 2.
Which ordered pair does not lie on the graph of this function?
A. (10, 32)
B. (8, 13)
C. (–5, –13)
D. (–8, –22)

Answer 1

b

Explanation:

Hi ok heres how I got it:

If the equation is y=3x+2, we just need to plug in each x and y value and see which one doesn't work. Either that, or we can just locate it on the graph.

For example,

10,32

Plugging it in gives us:

32=3(10)+2.

This is correct, meaning that A is NOT the answer.

Continuing testing, and we will find that B is the incorrect pair.

13=3(8)+2 is NOT correct.

13=24 is not equal.

Also,

-13=3(-5)+2 CORRECT,

-22=3(-8)+2 CORRECT AS WELL

Answer 2

The ordered pair does not lie on the graph of this function is B. (8, 13)

Explanation:

=> y = 3x + 2...i)

By putting the value of x in equation i).. from the options

firstly, putting the value of x = 10

=> y = 3(10)+2

=> y = 32

so, its the ordered pair that lie on the graph

now , putting the value of x= 8

=> y = 3(8) +2

=> y = 24 +2

=> y = 26

its 26, so the ordered pair does not lie on the graph of this function is B. (8, 13)
