Final answer:
The y-intercept of the equation y = -2x + 5 is 5.
Step-by-step explanation:
The y-intercept of a linear equation in the form y = mx + b is the value of the y-coordinate when x is 0. In the given equation y = -2x + 5, the y-intercept is the value of y when x is 0, which is 5. Therefore, the correct answer is D. b=5.
