Kerjakan nomor 6 dengan benar pakai cara

Answer 1

Verified answer

Y = 2px²
y' = 4px
garis g melalui (a, b)

gradien garis g
m = y'
m = 4px
m = 4pa

tegak lurus dengan garis g
m1 . m2 = -1
4pa . m2 = -1
m2 = -1/4pa

melalui titik (c, d)

Persamaan garis
(y - y1) = m(x - x1)
(y - d) = -1/4pa(x - c)
4pa(y - d) = -(x - c)
4pa(y - d) + (x - c) = 0
