Question

If the ordered pair (-5/2,y) lies on the graph of y=7-2x, find the value of y

A) 2

B) 19/2

C) 12

Answer 1

Y=7-2×(-5/2)
Y=7+5
Y=12
The answer is C

Answer 2

C)12

Explanation:

Hello, I think I can help you with this

in a ordered pair the first coordinate corresponds to the independent variable (x) and the second value corresponds to the depend variable(y), to solve this you can replace the value of x in the equation and then you will find the value of y

Step 1

Let

y=7-2x

x=-5/2

replacing

y=7-2(-5/2)

y=7+10/2

y=7+5

y=12

the value of y is C)12
