Answer:
-4
Step-by-step explanation:
We can find the slope when given two points by using the following
m = (y2-y1)/(x2-x1)
= (-7--19)/(-2 -1)
= (-7+19)/(-2-1)
= 12/-3
=-4
The easiest way to think about this is to give all of the numbers common denominators:
1 can be written as 6/6
0 can be written as 0/6
Now we can see that 5/6 is only 1/6 away from 1, while it is 5/6 away from 0.
So, 5/6 is closer to 1!
<em><u>Equation shows the relationship between distance traveled (d), speed (s), and time taken (t) is:</u></em>

<em><u>Solution:</u></em>
Given that,
Alice traveled 30 miles in 3 hours
<em><u>To find: Equation shows the relationship between distance traveled (d), speed (s), and time taken (t)</u></em>
<em><u>The speed is given by:</u></em>

From given,
Distance = d = 30 miles
Time = t = 3 hours
Therefore,


Thus the equation is found and speed is calculated
