Question 104736
Question: Make up a word problem that you can solve using a linear system. The solution is (5,35). 
:
Since you have a choice, choose a convenient slope, say +2, then use the
point/slope equation which is y - y1 = m(x - x1)
:
In our problem x1 = 5; y1 = 35; m = +2 (which we chose)
:
y - 35 = 2(x - 5)
y - 35 = 2x - 10
y = 2x - 10 + 35
y = 2x + 25; this our equation
:
Now think of the word problem that fits this equation.
: 
Example: You rent a U-haul truck. It cost $25 per day + $2 a mile
:
y = total daily cost, and x = number of miles driven per day
:
Therefore, if you drive it 5 mi (x) then cost will be $35 (y), right?
