Answer:
6/4
Step-by-step explanation:
ratio of x to y is the slope so
you can use butterfly method/cross multiply (multiply numerator on one side to the denominator on the other to bring all the terms up and then solve for y)
4(y+3)=6(x+2)
4y+12=6x+12
y=6/4x
so it would be 6/4

Answer:
Average call Becomes 15 minutes
Step-by-step explanation:
For Tom's Dorm to not run at a loss for switching to the new phone service the Average length of phone calls must not be less than fifteen (15) minutes.
Mathematically,
If he remains on his current phone line, a call of 15 minutes will cost :
= 0.1 * 15 = $1.5
But if he switches to the new phone line and makes a call for 15minutes, the cost will become :
First 2 minutes = 0.6 * 2 = $1.2
Subsequent 13 minutes will cost = 0.02 * 13 = 0.26
Total call for 15minutes on the new phone line = 1.2 + 0.26 = 1.46.
Since the cost became significantly lesser for 15mins when he switches to the new phone line, then the average calls Tom should make should not be less than 15 minutes.
