Answer:
x intercept is (45/2,0)
y intercept is (0,-36)
Step-by-step explanation:
Slope intercept form of equation of line is
y=mx+b where m is the slope and b is the y intercept
use any two points to find the slope
(10,20) (15,12)

m = -8/5
now we find out b using (10,20)

20 = -16 + b
add 16 on both sides , so b = 36
b is the y intercept , so y intercept is (0,-36)
Now we find x intercept
equation of line is y=mx+b that is 
To find x intercept plug in 0 for y

subtract 36 on both sides

Multiply by -5/8 on both sides


x intercept is (45/2,0)
2 or a few months. This should be the answer
Answer:
Did you ever figure this out?
Step-by-step explanation:
Answer:
im going to guess you didn't mean 1.240 miles but 1,240 miles
so we need to find how far they went each day so
1240/3=413 1/3 miles a day
Hope This Helps!!!
