What is the y-value when x = 0 in the function below?
y = x +1

To see which is the value when x = 0 in the function y = x + 1  we need to replace 0 where we write x, like this:

y = 0 + 1  = 1

Now, we know that when x = 0, y = 1, what does that mean in the function?

This means this function passes through the point (0,1), remember we write the points puting firstly the x and then the y, (x,y)

If we want to get more point, we replace the x:

If x = 1 --> y = 1 + 1 = 2 which is (1,2)

If x = 5 > y = 5 + 1 = 6  which is (5,6)
