Answer:
4y = -3x - 48
Step-by-step explanation:
y - y1 = m(x - x1)
y1 = -9 x1= -4 m = -3/4
y -(-9) = -3/4(x -(-4)
y + 9 = -3/4(x + 4)
y + 9 = -3/4x -12/4
multiply through by 4
4y + 36 = -3x -12
4y = -3x -12-36
4y = -3x -48 in the form y = mx + c

Answer:
c(x) = ($12) / x
Step-by-step explanation:
The general formula for inverse proportion is y = k/x.
In this specific problem, y represents the cost per person, k the dailyl cost ($12), and x the number of perople riding.
Then
c(x) = cost per person as a function of the number of people riding
= ($12) / x
Note that if only one person rides, that person pays $12/1, or $12; if two people, $12/2, or $6 per person, and so on.
Answer:
Step-by-step explanation:
If the number solution is none means, the two lines are parallel to each other and they will not intersect
If the number of solution is one, then the two lines intersect at one point which is the solution of the two equations
If there are infinite solutions, then the two lines coincide and so has infinite solutions.
