You have to use the order of operations when evaluating algebraic expressions. The m<span>nemonic device is PEMDAS, which stands for Parentheses, Exponents, Multiplication, Division, Addition, Subtraction. So the first thing is to solve what's in the parentheses.</span>
Slope of 2y = x + 5:-
This is y = 0.5 x + 2.5 in slope intercept form so its slope = 0.5
Slope of the line perpendicular to it = -1 / 0.5 = -2
it passes through (2 , 1) so we have
y- 1 = -2(x - 2)
y = -2x + 4 + 1
The answer is y = -2x + 5
