Question
Ana says that to find the distance from A(-3, 2) to B(-7, 5), you must evaluate the expression \(\sqrt{[-7-(-3)]^{2}+(5-2)^{2}}\). Emily disagrees. She says that you must evaluate the expression \(\sqrt{[-3-(-7)]^{2}+(2-5)^{2}}\). Who is correct? Explain your answer.
Solution
The first step in solving 6-7 problem number trying to solve the problem we have to refer to the textbook question: Ana says that to find the distance from A(-3, 2) to B(-7, 5), you must evaluate the expression \(\sqrt{[-7-(-3)]^{2}+(5-2)^{2}}\). Emily disagrees. She says that you must evaluate the expression \(\sqrt{[-3-(-7)]^{2}+(2-5)^{2}}\). Who is correct? Explain your answer.
From the textbook chapter More About Triangles - Distance on the Coordinate Plane you will find a few key concepts needed to solve this.
