1) The slope of the line 2) 1/2
Is the answer B? Hi
The Slope Intercept equation is Y=MX+C
Now y=ax+b y intercept =b(x=0) x intercept =b/a(y=0)
As per the original condition => b/a=2b Hence a=1/2
So the equation of the line becomes => y=x/2 + b Thus the slope of the line is 1/2
Hence the OA should be B.

Just an observation, to increase the speed for such questions, we can quickly check since the y intercept is greater than x intercept, the slope has to be negative, hence B is the answer.

How do we know slope is positive not negative here?

How? Please explain. You can use this formula to find a slope in Intercept form =\( \frac{{Y intercept}}{{X Intercept}}\)
