Question: 1 / 400

If the equation of a line is y = 3x - 7, what is the y-coordinate when x = 2?

0

-1

To find the y-coordinate when x = 2 in the equation of the line y = 3x - 7, you need to substitute the value of x into the equation.

Here's how it works:

1. Start with the equation: y = 3x - 7.

2. Substitute 2 for x: y = 3(2) - 7.

3. Calculate: y = 6 - 7, which simplifies to y = -1.

Therefore, when x = 2, the y-coordinate is -1. This matches the correct answer choice, which accurately represents the outcome of the substitution and evaluation process.
