Explanation
Plotting the lines y = 1 and x = 1, we get the following graph:
From the graph, we see that:
• the line y = 1 intersects the curve 3 times,
,
• the line x = 1 intersects the curve 1 time.
Answer
• The line ,y = 1, intersects the curve ,3 times
,
• The line ,x = 1, intersects the curve ,1 time
