If the lines are perpendicular to each other and the slope of the blue line is $$\frac{1}{2}$$   , what is the slope of the purple line?

If the lines are parallel to each other and the slope of the blue is -1, what is the slope of the purple line?

Choose the linear equation that is parallel to the following line

$$y=\frac{4}{3}x+1$$  

Choose the linear equation that is perpendicular to the following line

$$y=-\frac{1}{4}x-1$$  

Which of the following lines is PARALLEL to the graph of y = -6x + 3 and goes through the point (-1,4)?

What slope is parallel to:

m = 3/4
