Question

Which of the following statements best describes the graph of x + y = 2?

A. It is a line which intersects the x-axis at (2, 2).
B. It is a line which intersects the y-axis at (2, 2).
C. It is a line joining the points whose x- and y-coordinates add up to 2.
D. It is a line joining the points whose x- and y-coordinates add up to 4.

Answer 1

ok, when a line intersects the x axis, y=0
when a line intersects the y axis, x=0

so A and B are false because neither A nor B are 0

C, the x and y coordinates have to add to 2, ya
x+y=2, duh

D. no, 4≠2 so nah


C is answer

Answer 2

C; On this line, any two values have to add to 2.
