Question 1000428: Good Afternoon Ppl,
It's Sunday and I am stumped on 3 problems, please help. Thanking you in advance.
1. Write the equation for this situation: the cost, c, in dollars of a car rental is equal to 10 dollars plus 1/2 the miles driven, m.
2. Find the x- and y-intercepts of the equation. -3x-4y=18
3. Find the slope of the line containing the given pair of points. If the line is undefined, state so. (-4, -5) and (-4, 5)

You can put this solution on YOUR website! 1. Write the equation for this situation: the cost, c, in dollars of a car rental is equal to 10 dollars plus 1/2 the miles driven, m.
Ans: C(m) = (1/2)m + 10
---------------------------------
2. Find the x- and y-intercepts of the equation. -3x-4y=18
x-int:: (-6,0)
y-int:: -9/2
--------------------
3. Find the slope of the line containing the given pair of points. If the line is undefined, state so. (-4, -5) and (-4, 5)
----
Undefined because both points are on x = -4
-----
That is a vertical line.
------------------
Cheers,
Stan H.
