which equation represents a line that isperpendicular to a line that has slope -5? a. -x+5y=-10 b. -5x+y=1/5 c. y=-1/5x+4 d. y-10=5(x+1) give a reason

OpenStudy (anonymous):

the answer is A

OpenStudy (anonymous):

as its slope is 1/5......a slope of the line that is perpendicular to the one with slope -5

OpenStudy (anonymous):

so if the slope is -5 and line is perpendicular then the equation is -x+5y=-10 because the opposite of -5 is 5?
