Answer:
Third option, Slope of Function A is 2*Slope of Function B
Explanation:
Slope in function A= -coefficient of x/coefficient of y
Equation=f(x)=6x-1
y=6x-1
1=6x-y
Slope=-6/-1=6
Take any two random points from graph of function B,
I'll take -1,-2 and 1,4
Slope=(y2-y1)/(x2-x1)
=4-(-2)/1-(-1)=4+2/2=6/2=3
Thus, Slope of Function A is 2*Slope of Function B
