A rectangle is graphed on the coordinate grid. Which equation represents a side that is perpendicular to side d?
A. y = 2 x + 5
B. y = negative 2 x + 5
C. y = one-half x minus five-halves
D. y = negative one-half x minus StartFraction 7 Over 2 EndFraction

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.

other answer is correct. i had used the radius of the radius somehow. a website:

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
