Graph the relation shown in the table. Is the relation a function? Why or why not? x y
-1 - 3
-1 - 2
0 - -4
4 - 2

No; a vertical line passes through two graphed points.

Yes; no horizontal line passes through two graphed points.

Yes; no vertical line passes through two graphed points.

No; a horizontal line passes through two graphed points.

The chosen topic is not meant for use with this type of problem. Try the examples below.

x + 6 y = 5

6 x + 2 y = 8

x − y + 4 = 8

Use the given functions to set up and simplify  

2 .

x y =

− 1 =

3 =

− 1 =

2 =

0 − 4 = − 4

4 = − 4

2 = − 4

Step-by-step explanation:

Find the equation with a point and y-intercept.

y = ( y/ x  −  y )  x  +  x y

The chosen topic is not meant for use with this type of problem. Try the examples below.

( 0 , 9 )  ,  ( 8 , 6 )

( 0 , 9 )  ,  ( 5 , 4 )  ,  ( 1 , 4 )

( 1 , 2 )  ,  ( 3 , 4 )

i get you, what you should do is think of the positive things that would come out of it. it will make yours parents proud and raise your grade. you should always try and if you can't focus tell the teacher.
