Answer 1

When x, is 0, you just have to plug in 0 for x (and solve for y):
$y = -2(0)+1$
$y = 1$

So, your answer: y = 1

Answer 2

We have the following equation:
 y = -2x + 1
 For this case, the first thing to do is replace the value of x in the given equation.
 So we have that for x = 0:
 y = -2 (0) + 1
 y = 0 + 1
 y = 1
 Therefore, the ordered pair solution is given by:
 (x, y) = (0, 1)
 Answer:
 (x, y) = (0, 1)
 x = 0
 y = 1
