Question

a line makes intercept of equal magnitude and opposite signs on the coordinate axes .If itpasses through (-4,3),find the equation​

Answer 1

it's intercepts are (x, 0) and (0, -x) therefore equation will be ax + by + c = 0 or ax + x = 0 and -bx + c = 0

therefore ax = -bx or a = -b, now equation is ax -ay + c = 0, it also passes through (-4,3) therefore, a(-4) -a(3) + c = 0

-4a-3a+c = 0

c = 7a

therefore equation is ax-ay-7a = 0

Answer 2

Answer:

find the slope of a line having intercept of eqal magnitude but opposite in sign on the coordinate axes
