Answer:

Step-by-step explanation:
step 1
Find the slope
The formula to calculate the slope between two points is equal to

we have
the points (−1,12) and (1,2)
substitute



step 2
we know that
The equation of the line in slope intercept form is equl to

where
m is the slope
b is the y-intercept
we have


substitute in the linear equation and solve for b


therefore

To find the total cost multiply $12 x 180 square feet
Answer:
10 minutes
Step-by-step explanation:
Adam- 3 mph = 20 minutes a mile
Amy- 12 mph = 5 minutes a mile
Adam left 30 minutes prior to Amy so he is a mile and a half ahead before amy even starts.
30 minutes = 1.5 miles (Adam)
7.5 minutes = 1.5 miles (Amy)
but with this being said you have to continue to add time and miles to Adam because he's now gone an extra 7.5 minutes too.
45 minutes = 2.25 miles
15 minues = 3 miles
no youre too far and Amy is now further so we have to go back some
40 minutes = 2 miles
10 minutes = 2 miles
With all this being said Amy only needs to ride her bike for 10 minutes before she catches back up to Adam
