if 1 = -1 then..
2 x -1 = -2
-2 + 3 = 1

So if x = -1, then y = 1

Answer:

y = 1

Step-by-step explanation:

In the equation y = 2x + 3, y is defined as  a function of a variable x. As such, the value of y changes as the value of x in a manner defined by the equation.

To get the value of y when x = -1, substitute -1 for x in the equation

y = 2 (-1) + 3

= -2 + 3

= 1

This means that where x = -1, y = 1.
