thanks

Directrix (directrix):

The answer choices appear to have typos. Three equality symbols are missing, I think.

Directrix (directrix):

The line y=-3x+1 has slope -3. Any line parallel to the line above has slope -3.

Directrix (directrix):

Equation of line passing through ( -2, -1) with slope -3 --------------------------------------- y - y1 = m(x - x1) where m = -3 and (x1,y1) = (-2, -1) y - (-1) = (-3) ( x - (-2) ) y + 1 = -3 ( x + 2)

Directrix (directrix):

Your task is to simplify that.

y=-3-7

thank so much!!!!!!!!!!!!!!

>> y=-3-7 The variable x is missing.

Directrix (directrix):

y = - 3x - 7
