Answer:
Y=-1/2x ?
Step-by-step explanation:
There might be an y intercept. First find the slope. (Change in y over change in x) -2-1 over -1-5 then you get -3/-6. You can simplify an get -1/2. That forms an equation of y=-1/2x. That might be part of the answer. You still might need to find the y intercept, and I dont know how really. Hope this helps.
Runner L had the highest average speed
In this question there is a simple trick that needs to be handled first. Baring that simple trick the problem is very easy. The first thing that needs to be done after noting down all the details from the given question is to covert 1 hour to 60 minutes.
Time taken by Carla to travel 5 miles = 1 hour
= ( 1 * 60 ) minutes
= 60 minutes
Then
In 60 minutes the distance covered by Carla = 5 miles.
NOw
In 15 minutes the distance traveled by Carla = (5/60) * 15 miles
= 5/4 miles
= 1.25 miles
So Carla will travel a distance of 1.25 miles in 15 minutes.
Answer: b=9
Step-by-step explanation: To find the slope we use: y2-y1/x2-x1
Which would then be: 5-b/-2-7= 5-b/-9
Then we have to find a number for b that would give us -4 as the numerator. That number would be 9
This would give us 4/9 which is the slope we already had.
