Garis g melalui titik (1,2)Dan sejajar 4x+5y=40 persamaan gar is g adalah

4x + 5y = 40
5y = 40 - 4x
y = 40/5 - 4/5
m = -4/5 (x dibagi y)

sejajar = m1 = m2 = - 4/5

y-y1 = m(x-x1)
y -2 = -4/5 (x -1)
5(y-2) = -4(x-1)
5y -10 = -4x + 4
5y = -4x + 4 + 10
5y = -4x + 14

5y + 4x - 14 = 0
4x + 5y - 14 = 0
