4. From your equation, find the European equivalent for U. S. size 8.

equation~
m = (y2 – y1) / (x2 – x1)
m = (39-34) / (5-3)
m = 5/2
b=26.5
Equation = y=5/2x+26.5

Can someone please help me answer this? I have a graph if you need it... ps thank you for any help you can give!

To find the European equivalent for U.S. size 8 using the given equation:

The equation provided is in the form of a linear equation, y = mx + b, where:
- y represents the European shoe size
- x represents the U.S. shoe size

Now, we are given the equation y = 5/2x + 26.5.

To find the European equivalent for U.S. size 8, you will need to substitute 8 into the equation and solve for y.

Let's do that:

y = 5/2(8) + 26.5

First, calculate 5/2(8):
5/2(8) = 5/2 * 8 = 40/2 = 20

Now, substitute 20 into the equation:

y = 20 + 26.5
y = 46.5

Therefore, the European equivalent for U.S. size 8 is 46.5.

Note: If you have a graph, you can plot the points (x1, y1) and (x2, y2) mentioned in the equation m = (y2 – y1) / (x2 – x1). In this case, it seems those points are not provided, so we can directly use the given equation to calculate the European equivalent.
