Question

For an equally inclined line to the coordinate axes, why is the slope 1 or -1?

Answer 1

Answer:

because m is +1 or -1

Step-by-step explanation:

consider equation of line to be y=mx

where m is slope , for m to be +1 or -1 your line becomes

y=x or y=-x which means equally inclined

m is also called tan teta

for 1 and -1 the slope is 45 or 135
