Question

two lines are graphed on the same coordinate plane. the lines only intersect at the point (4,2). Which one of these systems of linear equations could represent the two lines select all that apply

Answer 1

If the two lines intersect at the point(4, 2), it means that x = 4 and y = 2

We would substitute these values in the equations. The correct options would be selected.

A is not correct because y is not equal to 4

B) 2 is not equal to 4 + 2. Thus, B is not correct

C) 2 = 4 - 2 = 2

4 = 2 + 2 = 5. Thus, C is correct

D) 2 * 4 + 4 * 2 = 8 + 8 = 16

4 + 2 = 6

D is correct

E is also correct

The correct options are C, D and E
