Which graph is a nonproportional relationship?
The slope of line CA is −23 . Which of the following is true about the slope of line XZ?
The slope of line XZ is the negative reciprocal of the slope of line CA because the triangles are flipped.
The slope of line XZ is one-half the slope of line CA because the ratio of corresponding sides between the triangles is 21 .
The slope of line XZ is the same as the slope of line CA because the ratios of the corresponding sides of the triangles are equivalent.
The is no relationship between the slope of line XZ and the slope of line CA.
