Answer:
Solving Quadratic Equations
- Put all terms on one side of the equal sign, leaving zero on the other side.
- Factor.
- Set each factor equal to zero.
- Solve each of these equations.
- Check by inserting your answer in the original equation.
Answer:

Step-by-step explanation:
We are given;
- A point where the line is passing through as (3, -4)
- The slope of the line -1/2
We are required to determine the equation of the line;
- Note that, one way we can get the equation of a straight line is when we are given a point where the line is passing through and its slope.
- Thus, in this case, we can determine the equation;
Taking another point (x, y)
Then; (x, y) , ( 3, -4) and slope -1/2 can give us the equation;
That is;

Cross multiplication;


Combining the like terms;

Thus, the equation of the line is; 
Slimplify 2-2/3 to 4/3
1/2*2-6*4/3
slimplify 1/2*2 to 1
1-6*4/3
slimplify 6*4/3 to 24/3
1-24/3
slimplify 24/3 to 8
1-8
slimplify
-7
Angle O is larger than angle QI hope this helps! ^^
