A parabola has a focus of (–10, 2) and a directrix of y = 4. What is the parabola’s equation? a) y = 1/4 (x - 10)^2 - 3
b) y = 1/4 (x + 10)^2 + 3
c) y = - 1/4 (x - 10)^2 - 3
d) y = - 1/4 (x + 10)^2 + 3

Given the equation y − 4 = three fourths(x + 8) in point-slope form, identify the equation of the same line in standard form. −three fourthsx + y = 10 3x − 4y = −40 y = three fourthsx + 12 y = three fourthsx + 10
