a.) A (5,6) dan (-4,-2)
b.) P (1,3) dan (10,4)
Tolong dibantu yah , Terimakasih !! (ノ・∀・)ノ
Jawaban dengan langkah-langkah:
A . Persamaan garis lurus = [tex]\frac{Y - Y1}{Y2 - Y1}[/tex] = [tex]\frac{X - X1}{X2 - X1}[/tex]
= [tex]\frac{Y - 6}{-2 - 6}[/tex] = [tex]\frac{X - 5}{-4 - 5}[/tex]
= [tex]\frac{Y - 6}{-8}[/tex] = [tex]\frac{X - 5}{-9}[/tex] ( Setelah itu kali silang)
= -9(Y-6) = -8(X-5)
= -9Y + 54 = -8X + 40
= -9Y + 8X = 40 - 54
PGL = -9Y + 8X = -14
B. Persamaan garis Lurus = [tex]\frac{Y - 3}{4 - 3}[/tex] = [tex]\frac{X - 1}{10 - 1}[/tex]
= [tex]\frac{Y - 3 }{1}[/tex] = [tex]\frac{X - 1}{9}[/tex]
= 9(Y-3) = 1(X-1)
= 9Y - 27 = X -1
= 9Y - X = -1 + 27
PGL = 9Y - X = 26
Maaf kalo salah ya :)
