Jom cuba! Let's see siapa dapat full marks! πŸ’ͺ
FORMULA PENTING KOORDINAT: 1️⃣ Jarak antara 2 titik:
Kalau x sama: Jarak = |yβ‚‚ - y₁|
Kalau y sama: Jarak = |xβ‚‚ - x₁|
Kalau both berbeza: Jarak = √[(xβ‚‚-x₁)Β² + (yβ‚‚-y₁)Β²]
2️⃣ Titik Tengah (Midpoint):
M = ((x₁+xβ‚‚)/2, (y₁+yβ‚‚)/2)
3️⃣ Kecerunan (Gradient):
m = (yβ‚‚ - y₁) / (xβ‚‚ - x₁)
4️⃣ Persamaan Garis Lurus:
y = mx + c
m = kecerunan, c = pintasan-y
5️⃣ Pantulan:
Paksi-x: (x, y) β†’ (x, -y)
Paksi-y: (x, y) β†’ (-x, y)

Hints? Given. Tips? Served. Formula? In your sheet.
Some of you: "OHHH finally faham!" βœ…
Some of you: "Cikgu I try but..." β€” acceptable, let's work on it 🀝
And some of you: proceed to kira gradient as (x+y)/2 then blames soalan β€” bro what are we doing wehh 😭
Susah sangat ke? Really? It's just x and y. Not x, y, z, your future, your hopes, your dreams.
Tell me where you lost. Then we move. Simple.

1. Koordinat-x sama (kedua-dua 3), jadi jarak = |9 - 5| = 4 unit βœ…
2. Titik tengah = ((2+8)/2, (4+10)/2) = (5, 7) βœ…
3. M = ((1+5)/2, (3+7)/2) = (3, 5) βœ…
4. Kecerunan (m) = (yβ‚‚ - y₁) / (xβ‚‚ - x₁)
m = (11 - 5) / (4 - 2) = 6/2 = 3 βœ… 5. y = mx + c
4 = 3(1) + c
4 = 3 + c
c = 1
Persamaan: y = 3x + 1 βœ… 6. m = (12-7)/(3-3) = 5/0 = tidak terdefinisi (garis menegak) βœ… 7. Titik tengah AB = ((0+4)/2, (0+0)/2) = (2, 0) βœ… 8. Titik tengah AB = ((0+4)/2, (0+0)/2) = (2, 0) βœ…

Faham ke atau just salin? Sebab salin tak payah otak, faham baru boleh buat sendiri.
One trip. One chance. Don't waste petrol on photocopy skills. ⛽️

PT3/SPM/ or any exam is coming. You know it. You feel it. But you still copy. Still lazy. Still "nanti lah."
Copy homework, copy working, copy answer β€” feels safe now. Feels like progress. But it's poison. Slow poison. You swallow it every day, thinking "asal boleh hantar" or "cikgu tak perasan."
Cikgu perasan. Cikgu tahu. Cikgu just tired of repeating.
Then trial comes. You blank. Panic. "I studied!" β€” no, you copied. You recognized, you didn't learn. Your brain never trained to solve, only to recall what others did.
SPM day: same panic, bigger stage. One shot. No retake. Result keluar, you blame "soalan susah," "nervous," "luck takde." Bro, luck favors the prepared. You prepared to copy, not to think.
15 minutes a day. That's all. Faham concept, then latihan. 15 minutes. You spend more time on TikTok, on reels, on "rest sekejap" that lasts 3 hours.
Your friends? Some grinding silently. Some already ahead. You? Still "esok lah." Esok becomes next week. Next week becomes next month. Then "alamak SPM next month."
If Continue like this β€” future done. Career done. Before you even start working, you're finished. Scholarship? Gone. Good course? Closed. Dream job? Someone else took it while you copied.
Don't trust me? Ask any senior. Not the one who peaked in school β€” ask the one who regrets. Ask the one who said "copy je lah, nanti faham." They never faham. Now they stuck, watching others fly.
One book trip your dad made. One chance. You're burning the fuel, burning the faith, burning your own time.
Wake up. Or don't. But don't cry when the fire reaches you. β›½οΈπŸ“šπŸ˜Š

Answer is no solution.

Wrong answer:
- Undefined
- x = 1

Explanation :

When obtaining the value of x = 1 by simplifying the fraction, if the value is plugged back into the equation it would be from

(x-1)(x-1)
β€”β€”β€”β€”β€” = 0
(x-1)

to

(1-1)(1-1)
β€”β€”β€”β€”β€” = 0
(1-1)

resulting in

0
β€” = 0
0

And the statement is simply false because anything divided by 0 is undefined.

Although, we cannot mark the answer as undefined since undefined simply means a value is not allowed whilst β€˜no solution’ tells us there is no value that makes the equation true

Hence, answer to the question is NO SOLUTION
