Question

Persamaan garis yang melewati titik A(-2 , -5) dan B (3, -7) adalah..

a. 2x - 5y = -29
b. 2x - 5y = -3
c. 2x + 5y = -3
d. 2x +5 y = - 29

pakai cara yaa, terimakasih :))

Answer 1

Y - y1/ y2-y1 = x - x1/ x2-x1
y -(-5) / -7-(-5) = x - (-2) / 3 - (-2)
y + 5 / - 7+5 = x + 2 / 3 + 2
y + 5 / -2 = x + 2/ 5
5y + 25 = -2x -4
5y = -2x - 4 - 25
5y = -2x - 29
atau 
2x + 5y = -29
jawaban D

Answer 2

Y - y1/y2 - y1 = x - x1/x2 - x1
y + 5/-7 + 5 = x + 2/3 + 2
y + 5/-2 = x + 2/5
5 (y + 5) = -2 (x + 2)
5y + 25 = -2x - 4
2x + 5y = -29 (D)
