Answer:
y = 4x + 5
Step-by-step explanation:
y - y1 = m (x - x1)
y - 1 = 4 (x + 1)
y - 1 = 4x + 4
y = 4x + 5
254 square unit is the answer
Answer:
3x²(4x-3)
Step by step explanation:
Factorise 12x³-9x²
first, find the HCF of the terms.
the HCF is 3x²
Then you can use the HCF to multiply all terms, each divided by the HCF.
3x²(12x³/3x²-9x²/3x²)
Dividing, we'll have
3x²(4x-3)
Since you are writing this in slope-intercept equation you will want to isolate the y. Therefore move the -8x over making it into -2y=8x+10. Then simply divide by the -2. And your equation will be y=-4x-5.
