Answer 2

To find the value of y when x = 0 for the linear equation 2x + 7y - 28 = 0, you need to substitute x = 0 into the equation and solve for y.

Let's do that:

2(0) + 7y - 28 = 0

Simplify the equation:

0 + 7y - 28 = 0

Now, let's isolate the term with y:

7y - 28 = 0

Add 28 to both sides of the equation to get y alone:

7y = 28

Finally, divide both sides by 7 to find the value of y:

y = 28 / 7

y = 4

So, when x = 0, y is equal to 4 in the given linear equation.
