Question

A(6,1) dan B ( 2,8)
TENTUKAN GRADIEN DAN PRSMAAN GRIS LRUS

Answer 1

M = y₂ -y₁
       x₂ -x₁

m = 8 -1
       2 -6

m = 7/-4

Answer 2

Gradien = (8-1)/(2-6)
     = 7/-4
     = -7/4
persamaan
y - 1 = -7/4 (x - 6)
y - 1 = -7/4 x + 42/4
y - 1 = -7/4 x + 21/2
y = -7/4 x + 23/2
4y = -7x + 46
7x + 4y = 46
