Question
Use a graphing utility to graph $ y_1 = 4 - x $ and $ y_2 = x - 2 $ in the same viewing window. Us e the zoom and trace features to find the coordinates of the point of intersection. What is the relationship between the point of intersection and the solution found in Example $ 1 $?
Step 1
The first equation is a straight line with a negative slope that intersects the y-axis at the point (0,4). The second equation is a straight line with a positive slope that intersects the y-axis at the point (0,-2). Show more…
