Point slope form: y-y1 = m(x-x1)
Find slope: (y2-y1)/(x2-x1)
(1-5)/(9+3) = -4/12 = -1/3
Point slope equation: y+5 = -1/3(x+3)
Slope intercept: y = -1/3x - 1 + 5
Final slope int equation: y = -1/3x + 4
Regrouping in subtraction means that if you can't subtract because the digit on the bottom has a greater value than the digit on the top (such as 3-6)m so in this case you would have to regroup twice.
Answer is B. x^7 - 4x^5 + 2x^4 + 4x^3 - 10
Here are a few rules of order
1. X values are always first, then y values
2. The highest exponent within that variable goes first (x^7 comes before x^5)
3. Numbers come after variables
Don't let the coefficients trick you since they are irrelevant if the exponent is higher. Automatically we know that -10 goes last because it is just a number. Then, you just order the x's from highest to lowest.
Answer:
D 6
Step-by-step explanation:
4/1 / 8/12
4/1 * 12/8
48 / 8 = 6
