Micah used the wrong sign for b in the formula x = -
za
OB. Micah should have evaluated the function with x=0 to find the
y-coordinate
OC. Micah did not use the correct order-of-operations dividing 475 by
21-95)
OD. Micah should have found a positive value when he simplified the
- 95(25) term
- 19
x-(-25)

ys - 59 375 - 118.75 +63
y - 115 125

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.

step-by-step explanation:

circumference divided by 3.141592654 then timesthe radius twice

definitely a. the others have almost all data points on one side of the line.
