Please...jawab yaa penting bgt niih

y = 5x + 2. ==> m = 5
a) 5x - y = 10 ==> y = 5x +10 ==> m = 5 (sejajar ksrena gradien sama)
b) y + 1/5x = 8 ==> y = -1.5x +8 ==> m = -1/5 (tegak lurus karena 5.-1/5 = -1
c) y - 5x - 3 = 0 ==> y = 5x +3. ==> m = 5 (sejajar karena gradien sama)
d) 2y = 10x + 4. ==> y = 5x + 2 ==> m = 5 (sejajar karena gradien sama)
