Answer:
m= <u>y2 - y1</u>
x2 - x1
m= <u>-7 + 3</u> ( I have + 3 and 4 because when negative cancel negative, it is
-2 + 4 positive)
= <u>-4</u> = 2
-2
Step-by-step explanation:
- write down the formula for finding slope.
- replace the y's and x's with the values.
- add everything together
- divide
Completing the square is done as follows:
1. Write the equation in a way that the constants are in the right side while the terms with x are on the left.
<span>9x2 +54x = 7
</span>
2. Make sure that the coefficient of the x^2 term is 1.
<span>9(x2 + 6x) = 7
</span>
3. Adding a term to both sides that will complete the square in the left side. This is done by dividing the coefficient of the x term by 2 and squaring it. Note: The same amount should be added to the right side to balance the equation.
<span>9(x2 + 6x + 9) = 7 + 81
9(x+3)^2 = 88
