Group points {(0,1),(0,5)(2,6),(3,3)}is not a function, but group points {(1,4)(2,7)(3,1)(5,7)} is a function. What do you notic

<h2>Any value in the domain of the function should have a unique value in codomain.</h2>
Step-by-step explanation:
In the first set of points 
,
value 
maps to two distinct values 
in the codomain.
This violates the property of functions.
The first set of points does not form a function.
In the second set of points 
,
Every value in domain corresponds to unique value in domain.
There is no violation in the property of functions.
The second set of points does form a function.
Answer:
y =2/3x -2
Step-by-step explanation:
The y intercept is -2
The slope is
m = (y2-y1)/ (x2-x1)
Using the points (0,-2) and (3,0)
m = ( 0 - -2)/(3 -0)
= (0+2)/(3-0)
= 2/3
The slope intercept form is
y = mx+b where m is the slope and b is the y intercept
y =2/3x -2
So I just set up a division for this question. I hope this helped and ask for any further help.
Answer:
Brother's money = $6
Money I have = $18
Step-by-step explanation:
Hi, to answer this question we have to write an equation with the information given:
<em>I have 3 times as much money as my brother:
</em>
Money I have = 3x
Where x is the money that my brother has:
Brother's money = x
<em>Our total is $24
</em>
So, 3x+x =24
Solving for x
3x+x=24
4x =24
x =24/4
x = 6
Replacing with the value of x.
Brother’s money = x = $6
Money i have = 3x =3(6) = $18
