What is the y-intercept of y = -2x + 7?

Explanation:
The y-intercept is the value of y where the graph 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, y = -2x + 7 has b = 7, so the y-intercept is 7. You can confirm by plugging in x = 0: y = -2(0) + 7 = 7. This matches the given value 7.
