1. gradien garis yang melalui titik A(0,-4) dan B(6,5) adalah........... A. 61 C. 32 B. 41 D. 23 2. gradien garis yang persamaannya 4x -2y = 6 adalah............ A. -4 C. 2 B. -2 d. 4 3. persamaan gareis yang sejajar dengan y = 2x -2 dan melalui titik (0,4) adalah.... A. y = 2x+4 C. y = -2x-4 B. y = -2x +4 D. y = 2x-4

Dik A = (0,-4) = (x1, y1) B = (6,5) = (x2, y2) m = ?
m = y2 - y1 / x2 - x1 m = 5 - (-4) / 6 - 0 m = 9/6 m = 3/2
2). 4x -2y = 6 m = - a/b m = - 4/-2 m = 2
3). y = 2x -2 m = 2 (0,4) = (x1, y1)
y - y1 = m(x - x1) y - 4 = 2 ( x - 0) y - 4 = 2x y = 2x + 4

A. Y2-Y2 = 5-(-4) = 9/6 = 3/2 C. X2-X16-0 B.M = -A/B -4/-2 = 2 C. C. Y=MX + C M = 2 Y-Y1 = M(X-X1) Y - 4 = 2(X-0) Y-4 = 2X Y = 2X + 4 A.
A = (0,-4) = (x1, y1)
B = (6,5) = (x2, y2)
m = ?
m = y2 - y1 / x2 - x1
m = 5 - (-4) / 6 - 0
m = 9/6
m = 3/2
2). 4x -2y = 6
m = - a/b
m = - 4/-2
m = 2
3).
y = 2x -2
m = 2
(0,4) = (x1, y1)
y - y1 = m(x - x1)
y - 4 = 2 ( x - 0)
y - 4 = 2x
y = 2x + 4
semoga membantu 6_^
X2-X1 6-0
B.M = -A/B
-4/-2 = 2 C.
C. Y=MX + C
M = 2
Y-Y1 = M(X-X1)
Y - 4 = 2(X-0)
Y-4 = 2X
Y = 2X + 4 A.
