Can you help me, here is the question: Draw a vertical y-axis on the left-hand side of your graph and label it. Then draw a horizontal
x-axis at the bottom of your graph. Then label the coordinates of each corner of the sign on your graph. Draw line a on your graph. What is the slope of line a?

and a second one: What is the equation of line a?

If you could, draw the graph also! thx
