Tentukan persamaan garis yang melalui titik (2,-4) dan (6,3) Please di jawab

gradien = (3 - (-4) ) / (6 - 2) 
= 7/4

y - y1 = m(x - x1)
y - (-4) = 7/4 (x - 2)
y + 4 = 7/4x - 7/2
4y + 16 = x - 14
4y = x - 14 - 16
4y = x - 30 atau 
y = x/4 - 30/4
y = x/4 - 15/2
- x + 4y + 30 = 0 
x - 4y - 30 = 0

x-2/y+4=6-2/3+4
3x+4x-6-8=6y-2y+24-8
3x+4x-6y-2y-6-8+24-8
7x-4y-2+16
7x-4y+14
