Question

if a line A is perpendicular to a line B WITH SLOPE -6 and its y intercept 4/3 then equation of straight line A will be                                                                                         (a) 6y= x+8
(b) 6y= x-8
(c) -6y= x+8
(d) None of these

help me any one

anonymous · Answer

Let's find the equation for line B
Slope: -6, y intercept: 4/3
y = -6x+4/3

anonymous · Answer

Then find the negative reciprocal of the slope of line b

anonymous · Answer

the slope of line b is -6, so the neg. reciprocal is 1/6
