Leo drew a line that is perpendicular to the line shown on the grid and passes through point (F, G). Which of the following is the equation of Leo's line?

line on coordinate plane passing through 0 comma 3 and 1 comma 1

y − G = −2(x − F)
y + F = 2(x + G)
y + F = one half(x + G)
y − G = one half(x − F)

Distance formula: the distance, d, between two coordinates  and  is given bygeometric definition of a parabola:   set of points on a plane that are the same distance from a focus point and a directrix line.let be the distance between the point  and the focus point at . using the distance formula: let be the distance between the  point  and  the directrix at , which is a horizontal line. when talking about this distance between a point and a horizontal line, we only care about the vertical distance. there is a point on the horizontal line that would share the same x-coordinate. sothese two distances must be equal: if we square both sides to get rid of the square roots both sides have  and 100; if we subtract those two from both sides of the equation: so
