Answer:
Line n: A set of points where the coordinates of each point have a sum of 2
Line m: A set of points where the y-coordinate of each point is 10 less than the x-coordinate
Explanation:
Given
Lines m and n (See attachment)
Required
Interpret both lines
First, we pick few coordinates of line m and then line n.
For m
-- At point E
-- At point B
-- At point D
For n
-- At point A
-- At point B
-- At point C
Test for Statement A:
Set of point with a sum of 2
i.e.

For m
-- At point E

This statement is not true for line m
For n
-- At point A

-- At point B

-- At point C

This statement is true for line n
Test for Statement 2:
Set of points where y is x - 10
i.e.

For m
-- At point E



-- At point B



-- At point D



This statement is true for line m
