Answer:
negative
Step-by-step explanation:
<span>Sasha
drove from her house to the grocery store in 20 minutes.
Her return trip took 15 minutes. IF the store is 7 miles from here house.
Find Sasha’s average speed for her round trip in miles per hour.
=> 20 minutes + 15 minutes = 35 minutes
=> 35 minutes is the time of her travel.
=> 7 miles is the distance.
We need to solve for the average speed.
Formula = Speed = distance / time
=> 7 / 35
=> 0.2
thus, her speed is 0.2 miles per minute (.2miles/min)

Answer:
A) 1.5
Step-by-step explanation:
You see, the slope is defined by y_2-y_1/x_2-x_1 so therefore if we look at 3 gallons of water and 4 gallons of water the y is length of string and x is water(gallons) so it's (4.5-3)/4-3=1.5/1= 1.5
