We can us a graphing calculator for this. We will enter the values for x into one list and the values for y into the second list. We graph the scatter plot and then run the regression. When we do this, we get
y = ax + b
a = 0.89370078
b = 0.53543307
Rounding to 3 decimal places, we have a = 0.894 and b = 0.535.
Yes, because when the side lengths of a triangle are in the ratio 3: 4: 5, then it is a right triangle. These sides are 6: 8: 10, then the triangle is a right one.
