Hello!
We can write an expression to show this scenario. Write this in the equation format y = mx + b:
m = rate of change, or cost per ride
b = initial cost, or cost to enter the fair
y = 2.50x + 4
Solve for the amount of rides possible with $21.50:
21.50 = 2.50x + 4
Subtract 4 from both sides to isolate x:
17.50 = 2.50x
Divide both sides by 2.50:
17.50/2.50 = 7 rides.
(1/2,-1/2)
You have to plug in the x point into the equation and the solution to that must equal your y point the only one that works for this is (1/2,-1/2).
-1/2=3(1/2)-2
-1/2=3/2-2
-1/2=-1/2. Works
-1/2=-(1/2)
-1/2=-1/2. Works
Hope this helps!
1/3 will be your answer. You always put Y above and X below. it moves 1 on the y axis and 3 on the x axis.
