WebStep 1: Identify h,k, h, k, and a a for the parabola in vertex form y =a(x−h)2+k y = a ( x − h) 2 + k through comparison of the constants. Step 2: Substitute the values from step 1 into the... Webon the directrix is the difference of the y -values: d = y + p. The distance from the focus (0, p) to the point (x, y) is also equal to d and can be expressed using the distance formula. d = √(x − 0)2 + (y − p)2 = √x2 + (y − p)2. Set the two expressions for d equal to each other and solve for y to derive the equation of the parabola.
