Will give brainiesta parabola has a focus of f(−11,5) and a directrix of x=−12. the point p(x, y) represents any point on the parabola, while d(−12,y) represents any point on the directrix. miguel was asked to use the distance formula to write an equation to represent this parabola. here is his work: fp=dp step 1: √(x−(−11))2+(y−5)² = √(x−(−12))2+(y−y)² step 2: (x−(−11))2+(y−5)² = (x−(−12))2+(y−y)² step 3: x²+22x+121+y²−10y+25 = x²+24x+144 step 4: y²−10y+2 = 2x step 5: 1/2y²−10y+1 = x all the choices are it is multiple choice step 4 is incorrect because a previous step is incorrect. step 5 is incorrect because he divided incorrectly. step 1 is incorrect because he used the wrong signs for the coordinates of the focus. step 3 is incorrect because he expanded the first binomial incorrectly. step 3 is incorrect because a previous step is incorrect. step 5 is incorrect because a previous step is incorrect. step 2 is incorrect because the square roots cancel the squares. only
