Question

Persamaan garis yang melalui A(- 3, 4) dan B(2, -5) adalah

Answer 1

M = -5 - 4 / 2 - (-3) = -9/5= -9
y - y1 = m(x - x1)
y - 4 = 9/5(x - (-3))
y - 4 = 9/5x - 27/5 |×5|
5y - 20 = 9x - 27
5y = 9x - 7

Answer 2

Y-y1/y2-y1 = x-x1/x2-x1
y-4/-5-4 = x-(-3)/ 2-(-3)
y-4/ -9 = x+3/5
5(y-4) = -9(x+3)
5y -20 = -9x -27
9x + 5y +7 = 0


semoga membantu kaka
