Question

Tolonnggggg bangetttt pakai diketahui ditanya jawab thankk youuu pakai cara yaaaa

Answer 1

Kelamaan pake diket, ditanya....

Lgsg jawab aja y..

4. Syarat tegak lurus = m1.m2 = -1
jika m1 = 2/5, maka m2 = -5/2

5. 4x - 2y = -8

6. x1 = -1 ,y1 = 4, m = 2.5

y-y1 = m(x-x1)
y-4 = 2,5(x+1)
y-4 = 2,5x+2,5
y = 2,5x+6,5 (tuh klo mau disederhanakan lagi silahkan)

7. x1 = 4, y1 = -2, m = -3/2
y-y1 = m(x-x1)
y+2 = -3/2(x-4)
y+2 = -3/2x+6
y = -3/2x+4

Good Luck! :D
