x = 4
y = 4² - 4 - 6
= 16 - 4 - 6
= 6
Jadi, garis singgung parabola berada di titik (4, 6)
y = x² - x - 6
y' = 2x - 1
2x - 1 = m
2(4) - 1 = m
8 - 1 = m
m = 7
y - b = m(x - a)
y - 6 = 7(x - 4)
y - 6 = 7x - 28
y = 7x - 22
memotong sumbu y, maka x = 0
y = 7x - 22
y = 7(0) - 22
y = -22
panjang M = |-22|
= 22 satuan panjang.
