Question

Persamaan garis melalui (-1,2) dan tegak lurus terhadap garis 4y = -3x + 5
please dijawab ya

Answer 1

M1 = -³/4
tegak lurus maka m1.m2 = -1
-³/4 . m2 = -1
m2 = ⁴/3
persamaan garisnya:
y - y1 = m(x - x1)
y - 2 = ⁴/3 (x - (-1))
y - 2 = ⁴/3 (x + 1)
3(y - 2) = 3 . ⁴/3(x + 1)
3y - 6 = 4x + 4
3y = 4x + 10
