Answer:
Slope is 2.
Step-by-step explanation:
So to find slope, we need to take the change in the y value, and the change in the x value, and then divide them. This may be confusing, so here is just 3 formulas in 3 seperate steps that we use to find it:
Step 1 -
Step 2 -
Step 3 -
So lets start by doing step one.
All we need is to look for two x values. Lets use 5 and 6:
6-5=1
So 1 is our change of x. This is our 1st step.
Next we can use 2 y values, note that these should be the 2 y values that go wiht the x values above. So this means we have to use -3 and -1:
-1-(-3) = 2
So 2 is our change in y. This is our 2nd step.
Now lets plug this into:
:
So our slope is 2. Completing our 3rd and final step.
Hope this helps!
Answer:
Greg lives 280 miles from the mountains.
Step-by-step explanation:
Given:
Time required to drive to the mountains = 8 hours.
Time required to drive home = 5 hours.
We need to find the distance Greg live from the mountains.
Solution:
Let the average rate while driving to the mountains be 'x'.
So rate while returning home =
Now we know that;
Distance is equal to Speed times Time.
So we can say that;
Distance while travelling the mountain =
Distance while returning home =
Now we know that;
Distance while travelling the mountain and Distance while returning home will both be equal.
so we get;
Combining like terms we get;
Dividing both side by 3 we get;
Substituting the value of x in any of the Distance equation we get;
Distance =
Hence Greg lives 280 miles from the mountains.
