Step-by-step explanation:
Take the general equation of a straight line
Here is the slope of the line.
So let's get the equation of the line in the question in the same form.
Add to both sides:
Add to both sides:
Divide by to get it into the general equation:
Now compare it to the general equation to find the value of . The value of

Answer:14
Step-by-step explanation:
A nickel is 5 cents (20% of dollar)
and a quarter is 25 cents (25% of dollar)
We have given a pile of 42 coins worth of $4.90
Let x be the no nickels and
y be the no of quarter
therefore
x+y=42 -----1
+
=4.90 ---2
Solving we get
x=14 & y=28
Therefore no of nickels is 14 & no of quarters is 28
