Question

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

equation of line b?

Answer 1

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
