gambarlah garis dengan persamaan berikut! a.y=4x-1 b.3y=6x+9

a. y = 4x -1
misal x = {0,1,2}
jika x = 0 maka y = 4.0 - 1 = -1
jika x = 1 maka y = 4.1 - 1 = 3
jika x = 2 maka y = 4.2 - 1 = 5
jadi HP = {(0,-1),(1,3),(2,5)}

b. Simplifying 3y = 6x + 9
Reorder the terms: 3y = 9 + 6x
Solving 3y = 9 + 6x
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Divide each side by '3'. y = 3 + 2x
Simplifying y = 3 + 2x
