cari turunan pertama diatas
2(y+5) y'=-8
y'=-8 / 2(y+5)
y'=-4 / y+5
ingat!!
gradien=turunan pertama dari persamaan
m=y'
jadi
y'=-4 / y+5
m=-4 / y+5
3=-4/ y+5
3y+15 =-4
y=-19/3
subtitusikan
(-19/3 +5)²=-8x+16
(-4/3)²=-8x+16
16/9 =-8x +16
16=-72x+144
72x=128
x=128/72
x=16/9
y-y1=m(x-x1)
y-(-19/3)=3(x-16/9)
y+19/3 = 3x - 16/3
y+19/3 = (9x-16) / 3
3y + 19 = 9x-16
9x - 3y -35 = 0
jadi persamaannya
9x - 3y - 35 =0
