Answer:
Catron's error is
"She did not follow order of operations"
Step-by-step explanation:
Catron evaluates the expression (negative 9) (2 and two-fifths)
That expression can be written as below

Catron's error is
"She did not follow order of operations"
The corrected steps are
Step1: Given expression is 
Step2: Convert mixed fraction into improper fraction
Step3: Multiplying the terms

Therefore solution 
The equation of a line is given by y = mx + c; where m is the slope.
The given equation is 9 - x = 2y
y = -1/2 x + 9/2
Therefore, the slope is -1/2 and the y-intercept is 9/2.
