Question

if a line is equally inclined to axes ,prove that its slope is +_1

Answer 1

When a line is equally inclined to the two axes it means the value of the y-intercept and the x-intercept will be equal though they may differ in sign. For example, the line will pass through (a , 0) and (0  , a) giving a gradient of:
(0-a)/(a-0) = -1

It can also pass through (-a, 0) and (0 , a) giving a gradient of:
(0-a)/(-a-0) = 1

The line can also pass through (-a, a) and (0 , -a) or (a, 0) and (0, -a)
