Question

If you solve an equation by graphing each side as a separate line, which of the following corresponds to the solution of the equation? a. there is only a solution if the lines are identical c. the y–coordinate of the intersection point b. both the x–coordinate and the y–coordinate of the intersection point d. the x–coordinate of the intersection point Please select the best answer from the choices provided A B C D

Answer 1

• d. the x–coordinate of the intersection point

Explanation:

The solution of the system with two lines is the x-coordinate of their intersection point.

a. there is only a solution if the lines are identical

• No, it gives infinitely many solutions.

b. both the x–coordinate and the y–coordinate of the intersection point,

• No, only the x-coordinate is considered

c. the y–coordinate of the intersection point

• No, only the x-coordinate is considered

d. the x–coordinate of the intersection point

• Yes, correct
