For the line y = 2x + 3, the y-intercept is which value?

Explanation:
The y-intercept is the value where the line crosses the y-axis, which happens when x = 0. In slope-intercept form y = mx + b, the constant term b is the y-intercept. Here the equation is y = 2x + 3, so b = 3. If you plug in x = 0, you get y = 2(0) + 3 = 3, confirming the intercept is 3. The other numbers would imply different intercepts that don’t occur for this line.
