To start, we can factor the "3" in the parentheses - then move the -4 over. So,
y - 4 = 3x - 3
y = 3x + 1
So the y-intercept of the equation is "1", and the slope is 3.
Using the Theorem of Pythagoras (a² + b² = c²)
Put in the values:
12² + 12² = 28²
Is it correct? (solve)
Nope! Because 12² + 12² = 288, and the square root of 288 is about 17, not 28.
The answer is no, 12cm, 12cm, 28cm cannot form a triangle.

X1 + x2 / 2 , y1 + y2 / 2
8 + x2 /2 = 6
So x is 4
9 + y2 /2 = 6
So y is 3.
Answer is B ( 4, 3)
