Hello!

  • Equation: y = 2.50x + 4
  • 7 rides.

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.

What type of line is the graph of y = 7? A) Vertical B) Horizontal C) Rising D) Falling
Vitek1552 [10]
Vertical line, because it doesn't have an x-coordinate unit of change so the line would just be straight and vertical along the graph (0, 7).
