Jessie graphed one of the lines in a system of equations: . If the system has an infinite number of solutions, which statements are true? Check all that apply.
Answer
A
Any point in the coordinate plane is a solution because it has an infinite number of solutions.B
Point (1, 1) is a solution because it is one of the points on the line already graphed.C
It is impossible to tell if (–1,–5) is a solution without seeing the other line graphed.D
Point (20, 58) is a solution because it results in a true statement when the point values are substituted into the equation of the line.E
When the other line in the system is graphed, it will share all points with the line already graphed.
