Answer:
The slope is 1.75 and the y intercept is 10
Step-by-step explanation:
y = 10 +1.75x
y = 1.75x+10
This is in the form y = mx+b where m is the slope and b is the y intercept
The slope is 1.75 and the y intercept is 10
Town A starts with 2in and has a rate of accumulation of 6in every 1 hour
Town B starts with 9in and has a rate of accumulation of 3in every 1 hour
If X is number of hours then:
2+ 6X= 9+3X
6x-3x=9-2
3x=7
X=7/3 is about 2 hours
