A quality analyst uses the quadratic equation y=x2+2x−8y = x^2 + 2x - 8 to model the deflection of a structural beam under various loads (xx). The y-intercept of the graph represents the initial deflection of the beam when the load is zero (x=0x = 0). Based on this equation, the y-coordinate of the y-intercept is ____.
