identify the vertex focus axis of symetry directrix direction of opening and lenght of the latum rectum of -y2 + 4x +2y +23=0 bradley

hi,

i'm 75% sure the answer is 1,1 to both lines.

have a great day

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl

it would rotate about 180 degrees.

idk
