Question

Tentukan gradien garis berikut.
a.y = x
b.y = -2x - 3
c.x + 2y - 1 = 0
d.-3x + 5y = 0

Answer 1

Y= mx+c --> m = gradien

a. m= 1
b. m= -2
c. 2y=-x+1
y= -1/2x+1/2
m= -1/2

d. 5y= 3x
y= 3/5x

m= 3/5

Answer 2

jawaban soal A
m = Δx /Δy
    = 1/1
    = 1

jawaban soal B
m = Δx /Δy
    = -2/1
    = -2

jawaban soal C
m = Δx /Δy
    = -1/2
 
jawaban soal D
m = Δx /Δy
    = -(-3)/5
    = 3/5
