Y=-3/2x+30
y-intercept =30
Slope -3/2
Rise -3
Run 2
You find the slope by putting the points in the formula y2-y1/x2-x1
when you plug them in it should look like this
-4 -1/8-8
then you would add or subtract, when you do you would get
-5/0
this can't be divide so the slope of this 2 points is undefined
Hope this helped
Given that the plane flies at 12mph
⇒ 1 hour = 12 miles
---------------------------------------------------------------------------------------------
Rewrite 1 hour as 60 mins
---------------------------------------------------------------------------------------------
60 mins = 12 miles
---------------------------------------------------------------------------------------------
Find 1 minute
---------------------------------------------------------------------------------------------
1 min = 12 ÷ 60
1 min = 0.2 miles
---------------------------------------------------------------------------------------------
Find 18 minutes
---------------------------------------------------------------------------------------------
1 min = 0.2 miles
18 mins = 0.2 x 18
18 mins = 3.6 miles
---------------------------------------------------------------------------------------------
Answer: The jet plane traveled 2.6 miles in 18 minutes.
