Question

Given y = 2x + 1.
a) Find y when x = 2

Answer 1

To find y when x = 2, substitute the value of x into the equation y = 2x + 1. So, y = 5.

Step-by-step explanation:

To find the value of y when x = 2, substitute the value of x into the equation y = 2x + 1.

So, y = 2(2) + 1 = 4 + 1 = 5.

Therefore, when x = 2, y = 5.
