Write 90 out of 120 as a fraction-90/120. Simplify that until you can't any more and you get 3/4 of the original price.
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;
