Hello guys. Why (A) and (F) are not true? How you broach the solution here?
Hello Avraheem,
I hope you are aware with x- intercept, y- intercept, slope of a line, Positive slop and negative slope
Back to the question:
Here the line m is a positve slop and it lies between 0 and 1 and we know that the slope of one perpendicular line is negative reciprocal of the other
So if slope of m = 1 then the slope of line n = \(-\frac{1}{1}\) =\(-1\)
Option A and Option F: The x intercept may not be always positive. We are given that the slope of the line m is positive and lies between 0 and 1. For this x intercept can be negative, positive or zero, whereas the y intercept always remain positive.
For the line n the x intercept and y intercept will always be positive
As there are are no. of possibility of x-intercept for line m ; so option F is also not correct
Thanks a lot. Last question, why line m can not pass through (0,0), which is neither positive nor negative?
