Step-by-step explanation:
Answer:
1. he took 8/12 for lunch, but 1/12 is left
2. she ate 2/5, but there's 4/15 left of the whole cake that is untouched
Step-by-step explanation:
i hope this helps, the wording is a little confusing to me tho
For this case we have that by definition, the equation of a line of the slope-intersection form is given by:

Where:
m: It is the slope of the line
b: It is the cut point with the y axis
By definition, if two lines are perpendicular then the product of their slopes is -1.
If we have: 

Thus, the equation is of the form:

We substitute the point:

Finally, the equation is:

Answer:

Numerator of the equation is 3*nDenominator is 4*p - 5*n The equation is m = 3n/(4p-5n)
Numerator = 3*n
Denominator = 4*p - 5*n
Equation = [m = 3n/(4p-5n)]
