My teacher wants me to graph this quadratic, but I have no clue how. Can i have some help? The problems she gave me are: (Each of these are different questions that need to be graphed) 1. x^2 - 6x - 7 = 0
2. x^2 - 10x + 9 = y
3. x^2 + 6x + 8 = y

hello

Step-by-step explanation:

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer

make sure you have version 2.50

try looking in the very back of the book : )
