Which graph represents the solution m > 4 or m < -2?

The equation y=mx+b is the slope-intercept form of the equation of a line. what is the equation solved for b? y-m=b y-mx=b y/mx=b y/m-x=b

Can someone tell me if this is perpendicular? !

Run a linear regression to determine an equation (y=mx+b y=mx+b)
