Lines a and b are perpendicular. The equation of line a is y= 1/3+ 3. What is the
equation of line b?

Answer: y= -3x -4
Step-by-step explanation: the lines are perpendicular, so
the slope of line b is the negative reciprocal of the slope of line a. So -3x
From the graph you see that the y-intercept is -4
In slope intercept form the equation is y= -3x -4
