Which ordered pair is a solution of y>2x-3? A. (-1,-5)
B. (1,-5)
C. (2,3)
D. (2,-2)

Step-by-step explanation:

Given

Substitute the values to verify which is correct

A. (-1, -5)

B. (1, -5)

C. (2, 3)

D. (2, -2)

we have

y>2x-3

now

For

A. (-1,-5)

-5>-2-3

-5>-5

It is equal. So false.

B. (1,-5)

-5>2-3

-5>-1

-1 is not greater than -5

So false

For

C. (2,3)

3>2-3

3>-1

3 is greater than -1

So True

For

D. (2,-2)

-2>2-3

-2>-1

-2 is not greater than -1

So false

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
