it is given that the equation is
[tex]y=3x[/tex]
so we know that the coefficient of x represents the slope of the equation if the equation is in standard form
that is y = mx + b
so the slope is m = 3
In the all four option we can see that 5 is the largest among all the coefficient of x
so
y = 5x + 2 will have greater slope.
also, we know that the slope defines the rate of change.
so the correct answer is option B.
