Question

how can we say product of the slope of x axis and y axis is -1​

Answer 1

Answer:

See…its an important concept .

the slope of two parallel lines is equal……example…if AB and CD are two parallel lines…then ..SLOPE OF AB = SLOPE OF CD..

But if two lines are perpendicular to each other..the product of their slopes is equal to ..(-1).. …example…if line AB is perpendicular to line CD…then. SLOPE OF AB. * SLOPE OF CD= -1.

Similarly…your question..X axis .is perpendicular to Y axis…so according to rule 2..the product of their slopes should be equal to. -1.. BUT HERE ONE MOR THING TO REMEMBER….THE SLOPE OF X AXIS IS 0..AND IF Y AXIS IS infinitive. …so the product of their slopes is 0..as 0 multiplied with any number gives HERE THE ANSWER IS 0….
