The total distance is given as 18 miles
she traveled at 45 miles per hour for 20 minutes
20 minutes = 20 / 60 = 1/3 of an hour
45 miles per hour x 1/3 of an hour = 15 miles driven
18 total miles - 15 miles driven = 3 miles left
she then drove at 20 miles per hour
20 miles per hour / 60 minutes per hour = 1/3 mile per minute = 1 mile every 3 minutes
3 miles x 3 minutes = 9 minutes to drive the final 3 miles
20 minutes + 9 minutes = 29 total minutes to drive to work
she left at 7:15
7:15 + 20 minutes = 7:35 am she arrived at work
Answer:
B
Step-by-step explanation:
To find the slope of the line, we do y2-y1/x2-x1. In this case, for line n, I used the points (0,0) and (1,2). This means the slope will be 2-0/1-0. Simplify this to get 2/1 or 2. Therefore the slope for line n is 2.
To find the slope of the line, we do y2-y1/x2-x1. In this case, for line m, I used the points (0,7) and (1,8). This means the slope will be 8-7/1-0. This will make the slope 1/1 or 1. Therefore, the slope for m is 1.
Therefore, the slope for line n is greater than the slope of line m.

Answer:
statement D is NOT true. 2 and 5 are integers, but 2/5 = 0.4 is not an integer.
Step-by-step explanation:
Answer:
slope=(y2-y1)/(x2-x1)
Step-by-step explanation:
slope = (-6-(-6))/(6-7)
slope = 0/-1
slope = 0
