How does the graph show the change from Line W
to Line X
?

(1 point)

There is a slope change from positive to negative and no factor change.

There is a slope change from positive to negative and by a factor of 3.

There is a slope change from negative to positive and by a factor of 3.

The slope is changed by a factor of 3.

Answer 1

Option 2.

From the graph, slope(W) = 1/3 and slope(X) = −1, so the slope changes from positive to negative and its magnitude is multiplied by 3.
