Q.

persamaan garis lurus

___

a. 2y = x

2y = x

2y – x = 0

a = -1, b = 2

m = -a/b

m = -(-1)/2

m = 1/2

b. 8x – 2y + 1 = 0

a = 8, b = -2, c = 1

m = -a/b

m = -8/(-2)

m = 4

gradien => 4

Soal A.

2y = x

y = 1/2x

m = 1/2

Gradien = ½

Soal B.

8x – 2y + 1 = 0

-2y = -8x – 1

y = 4x + ½

m = 4

Gradien = 4
