See my attachment and you know how to do.
Answer:
It is undefined
Step-by-step explanation:
Slope formula:
m = y₂ - y₁ / x₂ - x₁
m = 2 - 6 / 3 - 3
m = -4 / 0
m = 0
From this calculation, there is no slope because the two points have the same x variable, which will result to a no run.
It would be a vertical line.
Answer:
5 km.
Step-by-step explanation:
We have to calculate the distance if we apply the speed formula that would be the distance in a given time:
v = d / t
therefore, if we solve for distance it would be:
d = v * t
Now the speed is 6 km / h but the time must be calculated, it leaves at 9:15 and returns at 10:05, that is, there is no exact time but 50 minutes, one hour equals 60 minutes, therefore:
50 min * 1 h / 60 min = 0.833 h, that is, the child took 0.833 hours to get to school, now if we replace:
d = 6 * 0.8333
d = 5
In other words, the distance between the school and the house is 5 km.
