Final answer:
The y-intercept of the equation -y + 2x = 0 is 0.
Step-by-step explanation:
The y-intercept of a linear equation is the value of y when x is equal to 0. To find the y-intercept of the equation -y + 2x = 0, we can substitute x = 0 into the equation and solve for y.
When we substitute x = 0, the equation becomes -y + 2(0) = 0, which simplifies to -y = 0. Solving for y, we get y = 0. Therefore, the y-intercept of the equation is 0.
