The y-intercept is $(0,3/2)$ or $(0,1.5)$ .

Given:

$-2y=3x^2-3$

The y-intercept is the value of $y$ when $x=0$ . Substitute $0$ for $x$ in the equation and solve for $y$ .

$-2y=3(0)^2-3$

$-2y=-3$

Divide both sides by $-2$ .

$y=(-3)/(-2)$

$y=3/2$

The y-intercept is $(0,3/2)$ or $(0,1.5)$ .

This is also the vertex for this particular parabola.
