Question

Which graph represents a function with direct variation? A coordinate plane with a U shaped line graphed with the minimum at (0, 0). A coordinate plane with a V shaped line graphed with the minimum at (0, 0). A coordinate plane with a line passing through (negative 4, 2), (0, 0) and (4, negative 2). A coordinate plane with a line passing through (negative 2, negative 3), (0, 1) and (1, 3).

left 3, up 4
right 3, down 4
left 3, down 4
right 3, up 4

Answer 1

a line passing through (negative 4, 2), (0, 0) and (4, negative 2).

Explanation:

A function exhibiting direct variation MUST pass through the origin, (0, 0), and the graph must be a straight line. The answer that satisfies these requirements is

a line passing through (negative 4, 2), (0, 0) and (4, negative 2).
